"Craigslist killer" Philip Markoff was arraigned on grand-jury charges that include first-degree murder, robbery and two counts of armed kidnapping. As if Craigslist users needed another reason to feel jumpy.

Here's the backwards result of the legal crusade against Craigslist: The site never used to make money from its "erotic services" ads. But the service tells Valleywag that it's now planning to profit from porn.

Troubled by reports that accused murderer Philip Markoff found his alleged prey through Craigslist, a do-gooder has called for a boycott of the classifieds site. 61 out of a hoped-for 500,000 have signed up.

If the cliché about secret serial criminals is that they seemed so normal, and no one saw their attacks coming, then Philip Markoff could be the poster child for the stereotype.
