Ads asking for "rough sex" using romantic rival's ID lead to felony charges.
Jessica Davenport told police in Austin, Texas it started as a prank, but investigators said she broke the law when she posted fake ads about another woman on Craigslist.
Davenport, 21, is charged with online harassment, a third-degree felony.
In an arrest affidavit, she admitted to posting an advertisement about her boyfriend's ex-girlfriend in which she seeks out rough sex.
The ad included the victim's cell phone number and the street where she lived.
Additional ads posted on September 23 used the victim's phone number and advertised the selling of drug paraphernalia and sex toys.
The victim contacted police when she received a disturbing call on her cell phone in response to the Craigslist ads. She had also received several graphic text messages.
Police said Davenport also used the cell phone number of the victim's 9-year-old daughter in one of the ads.
The victim told police she now fears for her safety and the safety of her daughter.
Davenport said her boyfriend had been having problems with the victim, but the ads were only meant as a joke.
She told police she wanted the woman to receive the off-color phone calls.
