I got two accounts closed and it said the reason was "Fair Play Policy" and I don't know why. I contacted chess.com and after a few chats, chess.com didn't say anything. The last thing was "I’ve gone ahead and initiated an appeal on your behalf. As soon as I hear back I’ll let you know." and they never replied back ever again.
You are only allowed one account. That alone is a good enough reason for them to close your accounts.
