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

@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. :) –  Anna Lear 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

3mr.me is scraping at least Stack Overflow and English Language & Usage without following attribution rules.

For example,

  • http://3mr.me/what-is-the-origin-of-the-slang-kicks-meaning-sneakers/
  • http://3mr.me/how-to-copy-the-current-file-full-name-to-global-clipboard-in-vim/
  • http://3mr.me/what-does-the-term-empirical-praxis-mean/

are scrapes of:

  • http://english.stackexchange.com/questions/125733/what-is-the-origin-of-the-slang-kicks-meaning-sneakers
  • http://stackoverflow.com/questions/18755682/how-to-copy-the-current-file-full-name-to-global-clipboard-in-vim
  • http://english.stackexchange.com/questions/132261/what-does-the-term-empirical-praxis-mean

without (1) visually indicating that the content is from Stack Overflow, Meta Stack Overflow, Server Fault, or Super User [etc.] in some way; (2) hyperlinking directly to the original question on the source site; or (4) hyperlinking each author name directly back to their user profile page on the source site.

For (2), they are linking back ("Read More Details"), but are both using tinyurl and nofollow, so it's not a direct link.

They have this in the footer, but it doesn't meet SE attribution requirements:

© 2013 3mr.me. All rights reserved.

Except for third party materials and otherwise stated, this content is made available under a Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Licence. The original Author/Publisher name is mentioned above.

No notice that content is from Stack Overflow. No links to original question. Does identify original author. Does not link back to original author's profile.

Also appears to be scraping the related questions links.

Appears to be using the site as a giant advertising board for an Amazon Associate account. Not sure if there's a way to report that to Amazon...

Yet another one.

I actually came across it due to a spamming user who posted a link to their site twice in this question: Support offline data display in iOS app (10k only) with that link being to their copy of that question.

Checking out their home page today, they seem to be getting stuff pretty quickly; probably using the API. They also have Disqus comments active, and seem to get a bit of activity there, so they are apparently getting hits through from Google.

Doesn't respect the fourth requirement :

Hyperlink each author name directly back to their user profile page on the source site

Example :

Only 3/5 author profiles are linked.

ifmdb.com

Here is a description from the site, a pretty murky looking, badly designed FAQ page:

IFMDb is searchable database of messages which are legally posted on the internet forums by internet community, for internet community

To try to illustrate the cc-wiki breach, let's take for example http://android.ifmdb.com/IsEBDg6p0-set-a-new-views-margins-programatically.html. This page does not break attribution requirement 1, since there is a reference to StackOverflow (albeit not-hyperlinked). What is does breach is 2, as the link to the "full question" is a proxy between the original clone site and StackOverflow, e.g. http://android.ifmdb.com/fullpost-IsEBDg6p0.html has a nofollow and doesn't link back.

Furthermore, I believe 3 is breached as well, as only Unknown shows up as the author. To round it all up, 4 is not respected, as there is no reference to the original account from StackOverflow which originated the question – original question is here

Sure hope my assertions are ok. Thanks!

  • Rough translation into other languages (like German), might be Google translator.
  • Links that are part of text or users are kept: go directly and visible to Stack Overflow sites etc.
  • example: http://de.techerald.com/page/como-puedo-deshabilitar-resharper-en-vs-y-habilitar-de-nuevo.html
  • Update: On bottom of example is written (in German): This comes originally from this question (linked) on www.stackoverflow.com (linked). Thus it might not be a real misuse/ stealing.
