These scammers are everywhere. There is no way to tell when someone joins if they are a scammer. Protect yourself. Ask for photos, do not pay friends and family. They like the wanted section for easy prey. When they say to contact their friend, that should be a big red flag. I don't know what else to say about this. Try to use a little common sense. Some of the parts people are looking for are rare. Be suspicious of somebody that just happens to have your parts. Ask a few members if they know the person. Check when the member joined. Don't no what else to tell you.
