When retagging a question (either with the tag editor or with the question editor), I can't add the tag. This happens both with Chrome and Firefox.

Couldn't save tags because:

  • sorry, the 'linux' tag is not allowed.

sorry, the 'linux' tag is not allowed.

Other tag edits seem to work normally.

If has been added to the blacklist: no! That would be like blacklisting windows on SU.


We changed the rules so intrinsic tags are inherently blacklisted across all sites.

(an intrinsic tag is "apple" on apple.se, "wordpress" on wordpress.se, etc etc etc etc. See https://unix.meta.stackexchange.com/a/514/5132 for some more details.)

We can remove "linux" as an intrinsic tag -- "unix" is also intrinsic here -- but this means you will get questions tagged "linux" migrated here without the tag removed.

    Yes, please remove linux. Linux is only a subset of the site's topic (a very large subset, but still a subset). It's normal to have it as a tag. Apr 13 '11 at 11:11

  • Agree with Gilles. The example with Apple on apple.se is not the same. Single site, single subject, tag blacklisted :)

  • In a site called Tom & Jerry: why Tom should be blacklisted but not Jerry, or vice versa? Should be both or none, IMhO.

and were both blacklisted; I'm not sure why (I guess they're probably misused quite a bit, or at least perceived to be). We'll have to wait for a dev to read this I guess
