I remember a case in which someone signed a message with someone else's name, that was also used to scam. This is just as bad: it's common practice on the Collectibles board to ask for a photo with a handwritten username and the current date as proof of ownership.
You have single-handedly made this entire concept useless by doing this:


Was this part of the escrow deal? Even if the delivery would have happened, you would have no way to confirm this if either party says the other one didn't show up.

Why didn't you mention this to eseayan 19 days later, but instead just said you don't have the funds?

Admin can restore deleted posts, I assume the same applies to PMs. But eseayan should ask for that, either by sending a PM to theymos, or by opening a topic in Meta.

Do you have any idea how your account got hacked?
