MIAMI -- It's an Internet black book of sorts -- a Web site where women can post warnings to other women about men who cheat.

But now, one of the men bashed on the South Florida-based site is fighting back and heading to court to prove his ex ruined his reputation.

Survey: Should Web Sites Like This Exist?

Don'tDateHimGirl.com is an alleged database of men women shouldn't date. The site lets users post or search profiles of different men.

"It usually ranges from cheating, lying, womanizing, stuff like that," said creator Tasha Joseph. "We have about 520,000 registered members and there are over 7,000 guys posted on the site now."

One of those guys is Pittsburgh attorney Todd Hollis. He recently filed a summons in court and is threatening legal action against the Web site and Joseph for defaming him.

When searching for Hollis on the site, three posts are displayed. According to the site, each post has been seen by more than 1,000 users.

"To think someone would have a global platform to post damaging, untrue information, to be able to do so anonymously, is totally repulsive to me," Hollis said.

The posts claim Hollis has a sexually transmitted disease, he dated two people at a time, he's bisexual, and one user claims Hollis "is like a chocolate dream until you get to know him. His crib is a dump and he wears dirty clothes."

"Once you see that information, it spreads and it's almost impossible to remove," Hollis said.

"They can accuse you of being a child molester, a pedophile. Where does it stop?" said Hollis' attorney.

That's the question the court will have to answer.

Right now, Joseph's attorney said the law protects her client because Joseph is an interactive computer service provider and is not liable for unedited posts on her website.

"The Internet is the ultimate cyber forum and it is no different than a coffee shop or a bookstore where people hang out and talk," attorney Lida Rodriguez-Tasseff said.

Hollis is asking for more than $25,000 in damage and he wants the Web site taken down.
