I can confirm that cryptomus.com is shady at best and that they think that having a company registration is enough to make them a legitimate business. In reality cryptomus.com is likely a frontend to a business from Russia and the overzealous AML "verifications" are likely in hope that this would help them stay safe from authorities. On top of that they also demonstrate total ignorance of how Bitcoin works.
Although there are no confirmations, their request for KYC data for the payment processor makes them a bad choice, especially since we are talking about transactions of less than $1000, which are usually not subject to auditing, especially if they are random and infrequent, which is what happens with the payment processor. Their way of dealing with the forum and managing the campaign was bad, and there is no reason to use them, especially when there are better alternatives. @mexcycle Is there any update?
