Why someone would do that has a lot to do with WHO did it. Facebook collects more information on the people that use it than any other online service, They have their email, what they like and who their friends are. Make a copy of the web page for your records and demand that Facebook identify the user that put it up there.
The thing is there is no way to contact facebook. I changed my name on it so they couldnt find me and the account was deleted that made it.
They have a reputation for not answering email but here they are:
warning@facebook.com
info@facebook.com
disabled@facebook.com

Thanks man. You're really helping me out this time. I tried to call them about but they don't have a customer support. I am having some friends tract where the email address originated from so that I can take legal action against them.
