I hope this topic belongs here, if not just let me know and I will know better next time around. Quickly I wanted to find out if blocking an IP address is legal? Does it also work? Thank you for your help.
>well the thing is this person imitates my images, never actually uses mine.
I haven't actually seen your site or it's evil twin. And i'm sure whomever is bothering you is probably disturbed in some way. However if he/she is 'imitating' you in a satyrical manner rather than outright copying your work and palming it off as his/her own, then it is protected by the first ammendment. We may not like it but people have a constitutional right to make fun of us. On the other hand if it is slanderous or defamatory (he/she says insulting things about you that you can prove to be false0 then you can sue.
You cannot block the IP of an AOL user (or any proxy IP) without blocking a lot of innocent visitors. If you are having difficulty with an AOL user then you need to take that up with AOL. AOL traffic is far too valuable to throw away for one jerk.
