Lol, i checked that user's time of transaction in Doge's blockchain, if we convert that to bitcointalk's timezone:
He received the money a little bit before he joined bitcointalk(4 minutes) but it seems to be legit in one way cause if you download the PDF SUMMARY of the transaction on his fox.exchange order you can see that his order was created 5 hours before he did the bitcointalk post. Though the EDIT part seems suspicious, i guess they made him post a good review on bitcointalk after they sent him the money.

The user "paz-1991" seems to be some sort of admin i guess but since the last time he was around here was a few months ago i didnt even try to message him, but yeah he ignored people's complaints a few times.

Thanks for the bestchange post, i didnt see that until now, i really expect them to have a big role in stopping them to do these things.
