RandomUserHere Steelseries GG rings a bell, had it installed when i got banned too.
Came back after some months of taking a break and was banned for no reason too.
Wrote around 8 Tickets over the last few months, still banned.
I'm in the process of getting a lawyer about the issue atm, since my account had skins worth around 1000€ and i'm not willing to accept they just get away with that. Won't play the game after that because obvious reasons but i'm not accepting this behavior.
