Things to look out for on a scammer is 1...they WILL ask for $ up front before a face to face meeting. They'll make some excuse about being robbed or shot at before. 2...check their registration date. If it's very recent, that a tell and it'll lead ya back to #1. And 3...if the price is to good to be true than it is!
The only reason these scammers are here is because ppl keep falling for their tactics! Don't be that guy and use some common sense when making deals here
