= phenomenon =
I have pushed a lightweight git tag curl-7.21.0-7.fc14 with a wrong target. Now I am not able to (re)move the tag:

{{{
$ git push origin :refs/tags/curl-7.21.0-7.fc14
remote: + refs/tags/curl-7.21.0-7.fc14 curl kdudka DENIED by fallthru
remote: error: hook declined to update refs/tags/curl-7.21.0-7.fc14
To ssh://kdudka@pkgs.fedoraproject.org/curl
! [remote rejected] curl-7.21.0-7.fc14 (hook declined)
error: failed to push some refs to 'ssh://kdudka@pkgs.fedoraproject.org/curl'
}}}

= implementation recommendation =
Please either remove the tag completely, or move it to cd3104e where it belongs. Thanks in advance.
