Unfortunately, it is unprofessional behavior from that platform, but since they are based in the United States, you should know that you will be subject to a ban if you are on OFAC list, whether the site showed that or not.

You have to ask them what they will do with that money if I don't send you the documents. You can also say that you visit that country and you will return to a country where you can verify your account.

Generally, if there is no explicit statement that they will receive that money, then waiting is the best solution. "Your country may be removed from the OFAC list."
