I'll try to make this short without going into detail.
Basically at another forum I post at, we're having issues with a certain member. Now he hasn't been banned, but he has been stirring up issues in a MMOG that I play. I am best friends with a head person for this game, and they have tried to ban him numerous times but he continues to come back. I assume he would do the same on our forums.
So, here is what is happening. Each time he comes to the forums, his ISP appears completely different. SBCglobal, Comcast, Bell, AOL, etc... it's always a different provider. I know you can use a proxy to change your IP, but will it show up as using a different provider too?
Sorry if this sounds confusing. We just dont know if he is proxying, or doing something else to make this appear.
