I know this might sound fairly obvious but why is multis such an issue?
Surely it should be simple, if you are proved to be a multi, your IP address is banned... FOR LIFE.
There should be no place for cheaters in this game.
There are plenty of teams, Osef, BM, WST to name just a few that are able to play competitive servers without having multi accounts.
Anyone caught playing Multi accounts should be banned for life... period.
Is that so hard to implement Georgi Unknown
