Craigslist can be your enemy.

From All This Is That:

'One week ago today, Seattleite Jason Fortuny and a buddy executed a heinous prank. They copied a hot/hardcore sex ad from another site (along with the sad explicit photo) and placed an ad on the Seattle Craig's List as a "Women Seeking Men" ad.

Fortuny then published every single response , with their photos (in some cases, including photos of the responder's penises) and their personal data (names, email addresses, phone numbers, addresses, and worst of all, their written responses).

The trollers then invited readers to help identify the responders and add additional data. . .piling ignominy on the embarrassment, all the more because it was a sick ad, requesting rough trade, bondage, and humiliation. The original ad clearly originated from someone deeply involved in S & M.'
