You have the right so say that the guy gives the Money first.Write in your Thread "I dont go first" or something like that.Let your sentence look trustfull and gain some vouches.
I almost got scammed today by this guy called dreamer apparently his real skype has been hacked on his profile, and I asked the "scammer" that we could use a middleman and he kept reffering me to fake imposter middlemen, at the end he couldn't be bothered trying to try to trick me anymore so he just quit skype! I was glad not to be scammed!
just be more careful dude, take more precautions.
ya man i just got scammed today of $80 and might not get it back
