Stole money from me after I accidentally clicked "Turn on for Purchases" when paying someone back for a non commercial payment. The option just appears in the interface SLIGHTLY AFTER you select Pay, so it's quite easy to hit by accident if you're going through a long list of payment requests. I imagine this has probably happened to multiple people so if anyone starts a class action suit please include me. Support was not helpful at all; didn't even attempt to understand what happened.
