Welcome to the new world of internet anti-dating: the websites that are creating havoc as burnt women name and shame their ex-lovers, often posting compromising photographs of the men they once vowed they would spend the rest of their lives with.

Some might have said it was only a matter of time, but just four months ago the website Don't Date Him Girl arrived and, according to its Miami founder Tascha Joseph, it now gets around 580,000 hits a day worldwide. On this and its sister site, manhater. com, women can post messages and photos of erstwhile boyfriends, fiances and husbands warning the world (and particularly other women) of their every fault.

Nothing is held back, least of all full names, addresses, sexual performance and criminal records.

Hell truly hath no fury like a woman scorned, and Irish men aren't being let off lightly.

According to one disgruntled woman, Trevor from Dublin is a "cerebral narcissist" and "a complete fake."

"He's more to be pitied than hated really, because he is so insecure about himself that he has to make a fake personality in order to have friends, " she writes. "Underneath it all, he is completely cold and unhappy. Honestly, this is a dangerous man. Last time I saw him he threatened to cut my throat."

Gary from Belfast apparently held his wife-to-be hostage in her own home.

"Before I married him he held me all night, threatening to kill me and the pets as well as burn the house down . . . I am most lucky and blessed to be alive. Don't date him girl!"

Roger's ex admits she is an idiot when it comes to love, but he said she was the one he had been searching for all his life. "He swept me off my feet, then out of the blue he told me he didn't love me any more, " she records.

While the latter musing may be fairly harmless, the retailing of criminal activities is not, especially when there's a photo-fit to accompany it.

Already, a counter-website has been launched threatening legal action, called classaction dontdatehimgirl. com.

"This is a new web site where people can vent their feelings of hatred toward others. People can post their target's name, photograph and vivid details of why they hate them, " the site proclaims, asking victimised men to join them in their law suit.

But according to Tascha Joseph, the class action site was set up in October and they haven't heard anything since.

"Guys aren't too keen on it, " she admits. "But we do offer them the chance to tell their side of the story and add it to their profile."

There are now over 1,000 men named on the site, with nationalities ranging from America and Canada to Australia, Africa and Europe. As of yet, there are just a handful of Irish men named and shamed on the site, and none of them has as yet refuted the claims made against him.

Tascha Joseph, who hopes to have dontdateherman. com set up for the boys to vent their rage against women by the end of this month, isn't at all surprised at how quickly the site spread across the world.

"This is a global issue and something women everywhere relate to, " she says. "We're hoping that men will think twice before they cheat on women, because now there's a consequence and everyone will know they're a cheater."
