Since I can't report this player via support ticket, guess i'm forced to do it here.
Because for some reason, every time I login, it automatically signs me out right after.
This player bought his account, and is ruining ranked games. He's level 30 and hasn't played a single game until today, which he completely fucking dominated in. He has no mastery points on any champions either, and no, he wasnt just "playing bots or aram", the guy bought his fucking account and it would show it on his recently games played.
I will reveal his name as soon as a rioter responds.
