I was going through the "blacklisted user input" page on Physics, and I noticed that the standard intrinsic tag blacklist that stops users from entering the site name as a tag (e.g. ^physics$) was missing. Looking in to it, many older sites like Gaming, Cooking, Webmasters, Stats, TeX, Security don't have this blacklist. All new sites (regardless of the beta status) have it (try to submit a blank question with the site domain name as a tag and it'll give you an error).

Could the tag blacklist be enabled on all sites?

    I'm not sure [stackoverflow] should be blacklisted from SO. It's pretty popular.

  • @Mat: of course, there are cases where it doesn't apply. (though the [stackoverflow.com] tag needs baleeting). But places like Physics.SE certainly don't need such tags. Commented May 25, 2013 at 7:43
  • Oh. I hadn't encountered [stackoverflow.com]... looks like a mess. (Agreed your proposal makes sense. I'm not too hot about the [database-administration] tag on DBA.SE either, now that I see it exists.)

  • @Mat: In fact the SO tag pointed to [SO.com] in its excerpt and wiki, I edited it out. Commented May 25, 2013 at 7:52
  • Also note that, on this very site, the meta tag is used (at least according to its description) for questions specifically about this site, <meta.stackexchange.com>. Since the meaning of the tag is not subjective or dependent on any other tags, the meta tag does not qualify as a meta-tag (though I think it is a meta tag). It also identifies an on-topic subset of questions. (Unfortunately, people also use it to tag questions pertaining to other sites' metas, so it still might need to die...)

This is handled on a case-by-case basis. If your site has a term that can apply to all questions on the site and folks are persistent about trying to use it as a tag, post a request on your meta and we'll mark it as intrinsic.
