I can say its someone using 50+ accounts doing this intentionally.
Im complaining for for a year to gms about him but they do not investigate because they are friends with the kid and trust him.

Since using vpns is allowed its hard to point the finger at the guy and say its him.
But hes smart enough not to ever tell anyone how he does it and hops over to other accounts when he feels the heat.
He never uses it when hes on his main.

TIP: When you experience something like this in a match type /staff <text> and ask if they can watch the match.
