the syntax on the command didn't work but you were banned for the same reason I warned you about earlier: both crouchspamming and playing cover / running away

as a matter of fact you can even see that you play cover in the clip you linked

if you had come to the game chat to ask what the rules are, I would have answered all your questions. I don't use the game chat to warn people unless I've already seen them use the chat themselves. too many excuses about not having seen the warning if I put it in game chat. no such excuse stands when they are kicked from server. plus, kicking from the server makes a player come back. and when you enter, the rules are always the first thing you see.

breaking line-of-sight for any reason after the inital contact is cover use/abuse. after you see each other, do not break LOS. running away makes each duel take longer, it wastes peoples time(imagine if in KvK or Aimlabs the target went behind cover)

other forms of cover use/abuse include:
- jiggle peeking-- strafing back and forth from behind cover often with shotgun/wingman
- shoulder peeking-- constantly playing too close to cover, such that only half your hitbox is visible
- headglitch-- only head is visible

there are a few other rules about out-of-game behavior. if you agree to read and follow them I'll gladly unban
