I didn't handle it, but it being against the terms of their site wouldn't mean it's not allowed here.
I am not really referring to their rules but this also:
Services are added to this list when we come to believe that essentially no trades of such accounts are following our rules, which prohibit for example selling hacked accounts, accounts requiring KYC info, accounts created using stolen identities, accounts which cannot be legally traded, etc.
But thanks for the clarification. Gambling sites are not listed on the lists that I quoted this.
