Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

This question already has an answer here:

NB The following is a community-generated list of websites that republish Stack Exchange content without attributing it properly. It is no longer being maintained, because the procedure for reporting such sites has changed; see the duplicate for more information.

There are a number of license-violating clones of Stack Exchange sites popping up that use Stack Exchange's CC-wiki data without following our Creative Commons attribution terms. Those terms are linked at the bottom of every Stack Exchange webpage, and are also included as a .txt file in every data dump we produce.

Google now has a form for reporting content copiers that appear above the originals in search results.

Also, you can block unwanted sites from appearing in Google search from the search page itself:

The option to block a site appears when you click a search result and then navigate back to the search results page. Click the "Block" link next to that result to block all pages within the site's entire domain.

This post was created as an attempt to organize information originally posted in this answer. You may also be looking for the post for reporting copycat sites that outrank Stack Exchange in search results.

I have never seen the CAPTCHA page as often as I did when I was adding the existing 40 or so answers to this question. – Pops May 8 '12 at 20:20
That is because you pasted. Try typing... Like a real person :) – Jeff Atwood May 12 '12 at 15:20
...yeeeeahhhh, I prefer the CAPTCHAs. – Pops May 12 '12 at 21:17
@JeffAtwood I would put a poison pill question(s) that only those APIs presented so that you could automatically re-scrap via Google and easily find infringing sites. Much like cartographers do on physical maps by putting fake locations or markers to easily spot copies. The thieves would never know what to look for and you could easily make this an automated process. – Jarrod Roberson Jul 14 '12 at 6:04
@Jeff is this handled at some level? Can we know which sites were reported and closed? – Shadow Wizard Aug 8 '12 at 10:58
@ShaWizDowArd I don't have a handy list of sites that have been dealt with, but we do monitor this thread and contact offenders. This post isn't just a black hole. :) – Adam Aug 31 '12 at 22:25
Is there a reason the original list of offenders was split into countless posts over multiple pages? Giving it its own topic, sure, but splitting into individual answers just makes searching for existing entries a PITA and invites duplicates. – Daniel Beck May 27 '13 at 8:49
@AnnaLear The RNQA site seems to still be going strong; here’s an ELU meta post about them scraping content from ELU. If there is anything more we can do, please let us know and we would be glad to pitch in in any way we can. Thanks. – tchrist Aug 4 '13 at 20:14

Update March 22, 2013:
This post was copied from It mentions the SO author's user ID, but does not say that the content is copied, or provide any link to the original post.

As of June 9th, 2013, they appear to still be ripping content from the Stack Exchange network; this question is copied from Arqade with no attribution:

They're still copying content as of August 4, 2013. This was copied from Programmers, and they didn't bother to strip out the duplicate notice:

The same people run, example: (from Why are the bridges of Klingon ships so steamy?)

Update Aug 9, 2013

An entire copy of the Movies.SE (give or take a few days) is replicated on

It not only copies the question and answer, but seems to make fake 'user accounts' that aggregate the data taken.

Also, http: //www. topic/ nzxp-two-photons-transition.html copied this answer from Physics.SE. This was reported here initially.

Copy content and even "generously" state it's CC-BY-SA. But no link back.

e.g. boldly copies How to sort the special offers list by relative discount?

The username links to a list multiple other questions by me, but there doesn't seem to be any way of knowing it's from ArQAde.

This one is a bit different,, it was posted as a pdf file instead of html. It is a complete copy of Starcraft 1 disc 2 isn't continuing the installation .

As before, there is no recognition of this being StackExchange content and the usernames link to fake accounts.

This is the same as the zqna one. – Mechanical snail Jan 28 '13 at 20:53
zqna is gone, but rqna is still going. For example:… is a copy of… – Richard Deeming Mar 5 '13 at 18:45
rqna is still going alright:‌​qgrid.html is an exact copy of SO: how-to-put-both-image-and-text-into-a-cell-for-jqgrid without any contribution or link to the original SO question. – François Wahl Mar 26 '13 at 9:47

  • copies all user pages, questions, etc.
  • no attribution
  • adds ads (inline text links and block ads)
  • uses trademarked images and cdn resources
  • purports to be Stack Overflow (contact page) Ironically even offers SE as a login

Site is pretty egregious, direct copy, user profiles and everything. Only site with 100% user profile copies that I have found. Even uses the favicon.

At first the site wouldn't let me view (said I had reached my maximum or some message along those lines), and I had to delete the cookie on my machine from them in order to access the page. Once I realized it was a copy I stopped browsing because of the malicious nature of the owner.

We are keeping an eye on this one and beefing up the blocking on our end. – Adam Jul 15 '13 at 21:35
@AnnaLear There's now a Server Fault version :o – Doorknob Jul 20 '13 at 4:03
How come is sending me back to Stackoverflow? – Louie Aug 1 '13 at 7:45

  • Example ( (Original on SO: ASP.NET MVC 3 Razor Syntax question)
  • No attribution
  • No links
  • They mangle the original text (e.g. leave out salutations)
That site is actually taken questions from all the popular websites and showing only the question and a link to jump to the main website for answer. – Ali Adravi Oct 20 '12 at 15:46
Interesting that the website in your profile is, another copycat site... why would you use both that and SO? – Pops Oct 30 '12 at 9:47

Why does $($) crash my page?

is the original; here is the copy:

Beating jQuery addiction: Which jQuery methods are easily translated into pure javascript? original

Copy: which the owner of the site takes credit for... methinks Felix Kling will not be impressed.

All content from this site appears to be ripped from SO.

This site appears to be owned and operated by this SO user.

More examples:
ORIGINAL: "javascript:void(0);" vs "return false" vs "preventDefault()"

There's a post about this at the high-Google-ranking copiers question as well.


It appears he is keeping tabs on us and removed this questions linked. Here is a quick example of how you can search his "most visited" questions (grab a chunk of code and/or text and google search)

Using JQuery hover with HTML image map

The question has been changed slightly. The answer is exact. There are literally hundreds of scraped pieces of content on this site. Too much for it to be cross-post coincidence


I Just re-visited him and his 'newest' questions almost all seem legit? However there are still legacy scrapes on his site with names/times/people changed but not intellectual property.

Check checkbox checked property using jQuery



How can I make a redirect page in jQuery/JavaScript?


Most efficient way to clone an object?

Really, after you find a bogus Question/Answer combo just click on the 'user' who posted it. All other content from said user is scraped from SO - and there are MANY of these users all with 2/3 questions / answers - I can't see it being an elaborate way for someone on that site to gain 'rep'

share copies my Server Fault question How to use tscon on Windows7?

EDIT:'s 'questions about English' branch appears to have scraped english.SE wholesale. In other 'questions about X' branches, the Xs all represent X.SE.

Update (Aug 13 2013): Site now links directly to and attribution to the site and CC-BY-SA is stated in the page footer. Case closed?


  • Example: duplicates Make Xcode 4 stop auto staging with git
  • Author names have been changed and maybe randomized (the question "author" on tips4all does not have the same list of "Questions Asked" as the author on SO).
  • No mention of, nor links to, SO that I can find.

They show you a question, and to get the answer, you need to view an offer. You don't need to click on it, there is a "skip" button, but they are hiding other sites behind their offers, so they get money for sending you away from their site.

Working from my previous answer (, I googled:

TypeError: unbound method can_move() must be called with O_shape

The first result was Stack Overflow (Python: Display Shape from Tetris Game), but the second was to that site:

Clicking "get complete solution" will bring you to an offer, clicking "skip offer" will then bring you to Stack Overflow.

P.S. I noticed that the questions on that site don't all go to Stack Overflow, they go to lots of different Q&A and forum sites :(

  • The scraper also purports to give a link "View original page at" (no further text), but this link goes nowhere. The scraper is presumably availing him/herself of a great deal of Stack Exchange content, a clearinghouse for SE content
  • This scraper site is heavily ad supported
  • Does state at the bottom that the content is licensed under cc-wiki and enumerates some (not all) SE sites involved, but does not link to the original question or the users.

A search for the term "Judaism" on their main site turns up over 600 hits on the subject, many, many of which (in a cursory search) are directly copied from Mi.Yodeya; a search for an active username turns up hundreds of hits, including questions, answers, and comments.

In addition, a search for "English Language & Usage" without the quotes turns up hundreds of hits (many from that SE site); searches for it with the quotes turns up 48; and searches for names with which I am familiar from other SE sites turn up content of those SE users.

The attribution is not only flimsy but actually incorrect. There's a disclaimer at the bottom of the main page (but over at Mi.Yodeya we believe it to be violating the license terms)

The content is from, and, and is licensed under cc-wiki. Any advice please contact us.


Confirmed, and I also see this site scraping content from Physics, e.g. this (original). Who knows how many other network sites they are taking from (without any attribution whatsoever). – David Z Jul 31 '13 at 1:42
Funny: the copies faithfully reproduce inter-post links back to the originating Stack Exchange site (see for instance my answer on‌​-so-long? which links back to The person who wrote the scraper is too much of a poser to even get that right. ::sigh:: You just can't get good villians these days. – dmckee Jul 31 '13 at 6:29

copies the content of SE sites without any attribution. For example, is a copy of this one on Math SE.

The site has the footer:

Copyright © 2013 - All rights reserved.

(Site first noticed by another user on Math.SE)

It's also pulling content from SF, and as far as I can see many other SE sites. – Michael Hampton Jul 17 '13 at 21:02

  • Example 1 from SO: (
  • Example 2 from SF: (
  • Full text of question, all answers (including marking accepted answer), and all comments
  • No attribution, no links, and no mention of SO, SF, or SE
  • Only reviewed a few questions but everything I looked at is from a SE site.

  • No mentioning that this material is from SE
  • No hyperlink to original question
  • No hyperlinks to user names
  • No attribution to authors or Stack Exchange
  • No links back to Stack Exchange
  • No mentioning that the content is licensed under CC BY-SA

After some brief investigation, it appears to pull from other Stack Exchange sites as well.


Scratch that, they're scraping from multiple sites now. I see at least a few questions from Photo.SE, and Sharepoint.SE. – fbueckert Jun 10 '13 at 14:23
One of their latest scrapes is completely blatant:‌​rces/ No attempt at all to reroute URLs. – fbueckert Jun 12 '13 at 14:37

Example: contains content from many questions and answers. At the time of this writing, the first question on that page is the AU question Iptables proxy host on port.

It goes as far as using the list of site tags and site name as headings/links, but does not indicate Stack Exchange as the source of the content. The four requirements from here are not followed.

It also inappropriately uses the Ubuntu logo.

Inappropriate use of the Ubuntu logo should be reported to Canonical as the trademark owner. See – ɥʇǝS Apr 7 '13 at 19:57

I googled my name "Rocket Hazmat" (keep the quotes), and this page was the 7th result. Not just the question and answers, they are also copying user names AND avatars with no links to the source!

I didn't post any, I just happened to have been the last person to edit 3 of the answers!) – Rocket Hazmat Jun 13 '13 at 14:08

The entire site looks like it was copied, but the real clue was, taken verbatim from SO:

It's quite funny, because in the answer I use my own name repeatedly as sample data. The post is attributed to "Peter".

I can find no indication anywhere of the content's origin. It's not a big site, but it's a blatant ripoff.

  • Displays completely different users for the questions/answer (seem to be non-SE users)
  • No link back to the source
  • Claims copyright:

  • On Gaming and on LoveVideoGame:

  • is a flagrant copy of Starcraft 1 disc 2 isn't continuing the installation . No recognition whatsoever that this is StackExchange material. They even stole the profile pictures along with the usernames.


  • Looks like it targets SO specifically. The listing pages seem to link to the original sources, but the individual pages don't. No other mention of SO or any other source, the license, or attribution.
  • No attribution
  • No link back


  •, original question: PHP x86 How to get filesize of >2GB file without external program?

  • No attribution or linkback to Stack Overflow; only mentions OP's username
Thanks for the report - these guys haven't improved and seem to have no intention of attributing, so their crawlers are now banned. – Nick Craver Apr 12 '13 at 2:37 ("IQwen question AND answer")
