You got an answer from Adobe. Adobe has means to detect fraud and high volume sales that are fraudulent, and in your case, Adobe's checkguards catched unusual sales patterns. The made an investigation, and they believe that they need to block your account.
They are saying you "until further notice" which means, I think, that they are still investigating. I think, they would say so, if the blocking would be definitive.
If you have no idea where the unusal sales come from, I suggest that you say so in a response to Adobe, and that you are interested in having your account unblocked.
In the meantime, you should concentrate on other projects. There is nothing that we here on the fora can do for you, and Adobe won't participate in this public discussion.
