As much as I think this was a very stupid idea, I don't know that there is anything illigeal about this?! (Hey, don't hold me on that, I'm no lawyer). Perhaps defamation about calling her a hooker (unless she litterally is). Or maybe harrasment... depending on what has been sent based on your webpage...

Anyways, hope you got your lesson! Between, why don't you just apologize...
