I can understand the pain in getting scammed, but that does not give you the right to spam the forum. You have already opened a scam accusation thread, you can ask default trust members to tag the fellow.
Two pieces of advice I would like to give:
1. Archive all posts of the scammer by using
archive.is for future reference as he may delete them and deny.
2. Instead of opening random threads opening here and there, post your experience in the person's sales thread itself.
