When will they remove the AFK bots that do 0 damage for long periods of time from the mixtape?

Despite several updates and anti-cheats, bots are still present.
It's impossible for even a beginner to not shoot at all in a mixtape, and beginners shouldn't be attracted to mixtapes where mixed matches are common. I hope a system-wide method for eliminating them is established soon.
