Beanie: Cheater used name Stephano(TM) when he got banned 2012. You can see it from the first pic. Name doesn't matter anymore when GUID gets banned in Master Ban Index. You can use whatever name you want but when you join a PBBANS server, the same GUID is still on the master ban index = autoban/enforced 1200 min kick.
Doesn't matter if you have hax on that time or not when you join the streamed server. Still autoban if you have the banned guid in use.
The IP is what that cheater used when he got banned 2012, again this doesn't matter if you use the same GUID. It's like if I'd take his cd-key and connect to our server, I'd get autokicked too. On that second screenshot where the Croatian flag is: It's not his IP but the IP where the GUID was used when it got banned.
No hacks
Different IP
Same guid
Edit: Yes Mishka you must get a new cd-key. I suggest you actually buy a new one, don't take it from "someone" because it will probably be a dirty GUID or someday will be.
