I will have to mention yahoo62278 here. Because I have seen their campaign thread in the forum and yahoo was their campaign manager then. I don't know if he still has their contact. You can also try to get them active here again and maybe promote if they find it worthy.
I don't think that will help. If the casino's so-called customer can't help, then I don't thin we should expect a former campaign manager or even the contact in this case. Those contacts are more of into marketing rather than technical team or compliance team.
OP, I would suggest you insist on asking them which exact terms of service you breached. It's broad to just generalize.
