I signed up as a customer and chose a freelancer to do some photoshop editing. Once we agreed on a price for the project, I had to put a deposit down, then I was asked a ton of personal information aside from just supplying a credit card for payment. Of course I declined, but was charged a bunch of fees that I've been unable to get refunded.
Used Upwork instead. All they require (like most normal businesses) is a credit card on file.
