Do you have pictures of him? Use ScamDigger to compare the pictures you have with others that are posted here. If you find a match, that means he's a scammer and you should post his email address, phone numbers, IP addresses and anything else you might have on him, in that thread.
If you don't find his pictures, that still doesn't mean he's real. Start a new thread and post what you have and we'll all help you determine if he's real or not. If not he will be exposed here to help others he's scamming (they do many victims at one time) and if he's real, his information will be removed. Unfortunately not many real ones get posted here. If your instincts are telling you something's not right about this guy, you are more than likely correct.
