Again, this is where moderation comes in. I sure don't advocate uncontrolled tagging.

However, whenever one avenue for "steam release" is removed, the steam just goes somewhere else-- and often under more pressure.

You're right... and just like an offending post or thread, can be easily dealt with.

Ironically, I've seen many, many insulting posts and thread titles stand, even after being reported, so the admin opposition to tags of a similar nature confuses me.
