fwiw, I've been accused of colluding (chip-dumping) by a much smaller site than stars. They sent me a list of players I was colluding with, then I went over every major pot I played with them and offered up explanations why this isn't chip dumping (like hey we got the money in on the flop and it was a fucking coinflip). I also made tons of passive-aggressive jabs at the monkeys that decided that this was a legit chip-dumping case and suggested they rework their "obviously flawed" process for determining these things.

I got my account back. YMMV etc
