Bunch of troller, afk, feeder, roaming aimlessly... Your report system is not effective. Dude just make the report system simply like a vote. Let's say If more than 3 people report this troller, then give this troller punishment. Suspend em by from playin by 15 minutes, 1 hour, then 1 day. EZ right? Or make a karma or behaviour point. Let's say each player have 100 points. Point reduce every-time they recive report. If the behaviour point reduce bellow 50 point they can't play ranked.
