My question involves defamation in the state of:

hi i'm new here. i joined here cause i really need some advice. this girl posted a webblog of me cause i'm made a fake account on myspace to trick her. she made it so i don't hurt the next girl but i never hit her or made any threats to her and she made claims that i would of hurt her and her kid which sickens me. so her and her friends are trying to spread the word. can i get her for character of defamation cause i fear this will damage me and i been laying low for a good bit. i haven't been haraased but the longer the page stays up the worst it could get. and do i need proof on how i found this webblog or can i just say someone told me about it? i just want the page taken down.
