Do you think the site audits all group access? And exactly how would they really investigate such a claim without any real specifics? In particular, the groups in question and the staff member that was supposed to have done it.
But maybe there is some kind of audit trail that could be looked at. At the very least, I would expect you to get some kind of response about the situation.
I gave them the message id's.
At the very least they could have contacted him and asked him themselves who it was. And if it turned out to be BS some warning or something could have been given.
But, as mentioned above, the main issue really is that Chess.com seems not to care that someone is claiming they are helping a team cheat.
I'm certain if I had a business and someone accussed me or one of my employees of doing something like this, I'd, at the very least, check into it and respond.
Its genious I tell ya. Material for my next book. There's SOoooo many leaks in that story, its like chess.com--Clinton Prison edition
The mods have to keep a tight reign on the groups in open population, or they'll be trying to sneak in contraban to the chess playa's in solitary confinement. 
I was in a group a while back, and the group was chattong about things when a staff member sent a private message to one of us talking about what were discussing
Once again, WHICH staff member did that ?
Don't tell me the message didn't have a sender specified.
