Thank you all guys for your time and effort. I have already received the information I wanted. These two nicks are pissing me off in the exact same way and I just wanted to know whether their same IP addresses would support my theory or not. I would not condemn them publicly, since, as you say, there's no 100% proof they're actually the same person, however, I made my own mind and that's what I had been aiming for.
Is there any way I can find IP addresses of people connecting to this site? I would like to know if two users who I think might be the same person use the same computer.
