Coming from you, I am quite surprised that you missed that it is exactly what Betcoin.ag did (and as far as I know, Nitrogensports pledged to give back the BCHs to their customers but has yet to make good on their words).
Worse than that, at no point did they advise their customers to cash-out before the fork to split by themselves their BCHs. Betcoin.ag just said they will act in the best interests of their players and... kept all the BCHs for themselves.
https://bitcointalk.org/index.php?topic=2152902.0Honestly, at this point, Betcoin has shown themselves to be such a criminal organization and I've warned people for so long about so many things that I have no sympathy for people who continue to give them their money. It doesn't surprise me at all that Betcoin stole all of their player's BCC because they've stolen so much from so many for so long.
