Tag evasion ban, are you serious?

[castiel]

Mael, you seem to accept that it's sometimes OK to ban a tag:

The only reason to block players from using a...tag is if [it] causes trouble.

...then advocate bypassing this ban. Which is it?
If I don't want a clan represented on my servers, for whatever reason, is that my prerogative or not? If a player bypasses my wishes repeatedly, is this not a reason to IP blacklist?
I know of a specific case that may have caused this, and the player in question was told that his clan-tag wasn't welcome, but insisted on bypassing that wish and goading the admin who was trying to enforce it. It was this poor behaviour that resulted in the IP ban.

So you warned the blacklisted players repeatedly?
