Waiting for an answer from the official representative of Coinplay, I think that the amount that you could not withdraw, that is, that remained in your account before it was closed, is not an important amount that one could risk losing his reputation for. Perhaps if there were other complaints about other users experiencing the same situation, the suspicions would be legitimate. But the platform has been working effectively since its launch and the signature campaign it runs proves that as well. I don't think they accuse you of trying to manipulate their system without obvious reasons.
By the way, why didn't you post your problem on their official announcement before accusing them directly in a this board?
