Got ban after afk at Gauntlet6

like the tittle, i play rush with my fds and go afk a few games in Gauntlet and i got a red ban at next day.

I mean, i know afk is not a good things to do, but tbh how the fxxk that a lot of cheaters kicking u out at DR, WL, Live event, like having  15w WL everyweek, top200 at sbq, using AI to play RUSH, losing at Live event then kick u out to disconnect, and bro they are still having fun in game with like no risk, like cheater everywhere and u tell me that i got a red ban just for chilling with my fds to play rush, i got a red ban just for afk few game in Gauntlet?

I started thinking maybe i gonna buy a cheat to play this game can get much more fun, happies, enjoying this game, how do u think EA?
