2. Then ask the person where they live when they tell u a state or something say that you live in the same state and would be willing to pick it up if they dont want to meet face to face then they are problably a scammer.
3. if u do decide to buy never pay as a gift or donation always goods or service
4. always make the person provide a tracking number
5. the only people you trust without making them go through this process are people with a Trusted seller. admin. or moderator badge

You can't trust anyone even if they have a "Badge". Remember Koonmodz or ghettoman? They both were high up on here and they scammed people and even if they are trusted, you don't know if they will rip you off. I would suggest sending your payments as a good, if you get scammed you just show proof and you get your money back. Simple.

I have never been scammed, even in the mw2 early ages, no one could trick me. I only trusted myself, and all others I thought of as scammers. If you wan't something so bad, do it yourself. (lobbies, ex.)
