You'd have to change the PC or the mottherboard to connect to gog again.
Nah, just connect via a new or other VPN service or perhaps just go through TOR then refresh the connection to get a new IP.
An escrow system would be good enough, the hard part is to put it to together because usuaully such a service takes a cut I think.
Aren't motherboard IPs usually unique to the motherboard? I thought you can't simply change that. Tracking that IP and banning it , would stop him from at least connecting with gog. I may be wrong , but it has worked on me. I got banned from PlayFire for fighting 360 fanboys and I still can't connect with it.
If banning PC IPs doesn't work , there's always the banning of the email address , which is a lot easier.
Until the escrow decides to bolt with both of the trade items or turns out to be a scammer plant.
Yes but then that person or system loses the reputation and for what? Two codes as video games. What a reward..
It is a reward if they're 2 60$ game codes :P xD , but you\d be mad to do it even then.
