*throws in 2p*
ektaone if your not the person involved why get bothered over it? You said it yourself you reported it to the staff, they looked and decided not to action on it (simply by the fact its still there).
I'd assume you've already informed the person it involves, and if you havent you should of. It's upto them to take legal action. Whether your a friend of the person, or just a bystander, you can not take legal action on thier behalf, they have to do it themselves. And frankly if they cant be bothered to do anything about it, then you should let the matter drop.
I've been a victim of similar stuff over the past 5 years, as a member of one of the UK's only officially recognised pagan temples im frequently featured on christian sites as a focal point of hate. I could sue, but frankly i dont see the point, for every site you take down another can be put up. One site actually did a full defamation of character that included both racist and sexist comments. Was i offended and hurt over it, sure i was, and i even consulted a lawyer. His reply was that he'd be happy to sue. Problem was that as soon as its down it'll most likely reappear elsewhere and i'd have to start all over again. I could apply to have a restraining order, but at the time it was a cost i couldnt afford, and again i didnt see the point.
Finally, its been up for 9months with no activity, just let the matter drop. Keep dragging it out over and over only publicises the matter more. If the person its aimed at isnt going to sue, just drop it and let it die. It's not worth the ulcer.
