And I'm assuming that these players have been reprimanded or even banned for trying to enforce the knife-only rule on the server already.
I'll further venture to guess that they also harass the ever-loving shit out of players who don't want to do knife-only. Just my experience with certain regulars.
These players know that the rule is unenforceable, and that if you enforce it, you're putting your admin status on the line, yet they still ask you to enforce it-- They're not your friends.

This gets brought up every once in a while, general consensus is that we'd add a plugin, but it would only be usable by ULA or clan.
Point those regulars towards this

If they think knife-only would be so popular it's worth ibis putting in the time and effort implementing that plugin and then testing it.. maybe it's worth them opening their own knife-only server? They could make millions!
