Probably nothing that you can do, it is very strange for you to have picked that affiliate program, most people go with the 20% revshare. When people sign up for the pay per registration program it just sends red flags all over the place specially if no one actually buys tokens. People often pick that affiliate program and try to trick CB with fake registrations but jokes on them cause CB has spent many years now fighting fake traffic.
Even if you didn't try to do any fake registrations programs like that will often remove you from the program if they aren't satisfied with the results. The 20% rev share i mentioned is the best program they offer in my opinion.
