OK. I really think the moderators should go ahead and take action right now.
The evidence seems to be more or less solid. Not to mention the accused user has had several complains about this exact topic previously (scam)
It seems rather reckless to let him keep going right now. Regular users have a scary way of showing waaay to much trust in contributors. The fact that you can PAY to let your title say "professional seller" does not help at all.
Give Resp3ctcho some peace of mind and finish this now.
