Why is https://site.com/ and https://mysite.com/ blocked from the post content on the main site?

I tried to make a sample URL and I had to use https://testsite.com instead.


1 Answer 1


Use the URLs that are reserved for this purpose: example.com, example.net, example.org. See: Wikipedia's article "Example.com".

site.com and mysite.com are blacklisted network-wide. These sites appear to be created for the express purpose of driving traffic to those sites from folks who want to use them as example URLs.

abc.com is also blacklisted. If you want to refer to the American Broadcasting Company's website, use abc.go.com.

For details, see: Help users create dummy links that are not to unrelated commercial sites

    maybe an improvement is to add that as an alternative. "site.com is blocked. try using example.com instead." Commented Nov 26, 2013 at 0:22

    @DanielA.White Or replace instances of that with example.com. Commented Nov 26, 2013 at 0:23

    @RobertHarvey what about having an official meta page that is linked to? Commented Nov 26, 2013 at 0:23
  • It's merely two of several blacklisted terms.

    @RobertHarvey the biggest problem with the way it is, it doesn't explain why. Commented Nov 26, 2013 at 0:24

    Please note that example.com, example.net and example.org are also self-explanatory and points to iana.org - pretty much the highest authority in the matters of domain names :)

    It's ironical, you drive traffic to those sites writing how bad they are driving traffic from some folks ;) Commented Nov 26, 2013 at 12:16

    @RobertHarvey I think Daniel was just asking that the message saying that it's blocked also suggests example.com (which shouldn't be hard to do). Commented Nov 27, 2013 at 18:17
  • @Dukeling: The blacklisting system accepts a list of regexes that identify the blacklisted terms. Calling out one of those terms specifically would require modifying the blacklisting system itself; you can't just stick a custom error message in there for one particular term.

  • @RobertHarvey My guess is that URLs are a big enough thing such that it can be treated separately (but it's a guess, since I don't have access to that data). Won't it be simple enough to simply make two calls to the blacklisting system (or however it works) with 2 regexes displaying different messages (one for URLs and one for the others)? To figure out the right URL to replace your blocked URL with can involve a bit of effort (and possibly a few Meta questions for those who didn't extensively search first, which need to be answered).

  • Or, y'know, you can do what the error message implies, and simply try something else.

    Sure, anyone should be able to find a domain that works, but it would be better to have them use the correct domain (if for no other reason that to prevent the work caused by answering Meta questions about it, blacklisting new domains and changing the domains in questions). So it may not be worth the dev time or additional overhead, but it's worth a consideration. Commented Nov 27, 2013 at 18:41

    And why is that a problem? No one is forced to click a link. I just entered abc.com which also was blocked and I am pretty sure ABC didn't register that site to receive illegitimate traffic. I don't like all these "protect the users from themselves" attitude and rules on stackexchange.com. We need more darwinism on internet.
