Posting here in hopes that this reaches someone that still worry about the game and has the means to do something about it.
People have been using an exploit that makes you able to put more characters than available in your nickname, then, they'll name change and pump a bunch of spaces before their actual nickname.
Why is that important?
Cause that makes the system not able to give or take LP from them after the game ends, so, they are playing 12+ hours a day inting games to drop their MMR to low elo after reaching Challenger (not in a legit way), to then play against low elo players winning every game while still gaining 20+ LP, exploiting their way to Rank 1.
Here you can see it in action:
