Yeah people who ask you to pay first and not offering an escrow cannot be trusted. I deleted him from skype once he said I have to pay first. deal with this user at your own risk.
I could send the code upfront, but just for trusted members. I am new here, but not new in other well know forums. As I said before I can show my other forum profile, which is very trusted.
You do know what an escrow is right? its the only way to deal with users you don't trust. it removes all doubt of scams and shows the person who is willing to use it is likely trusted and those who refused are 100% scammers.
