Topix not removing slanderous threads...?

3 weeks ago I found out this weirdo from school posted a bunch of demeaning lies about me on some gossip site called Topix, I reported it under an hour from the time it was posted, it has now been 22 DAYS & although my friends & I have reported it/asked it be deleted many many times throughout this entire time, it still remains visable & open for the world to read, what can I do to get it removed??
