We have developed a model for checking transactions so that the probability of suspending a customer's order that is not related to a crime in any way is minimal.
Wouldn't it be much easier if you share the results of said model before depositing? So I inform you about the address I'll send funds from, and you tell me whether or not my funds are going to get frozen. It saves me the hassle of having to provide paperwork, and you don't have to spend time on providing evidence. But most importantly: I'm sure I don't lose my money depending on the decision of an anonymous website.
This whole setup makes it look like vigilante justice: you trick "criminals" into sending their funds to you, after which you decide what to do with it.
