A Library of Congress film preservation worker faces federal charges for allegedly posting fake sex ads on Craigslist directing men to his ex-girlfriend.

The Star Exponent of Culpeper reports that 61-year-old Kenneth Edward Kuban was charged with stalking a Fauquier County woman he had dated briefly in 2011.

Kuban, who works at the Library of Congress Packard campus in Culpeper, allegedly posted the ads from his work computer.

Authorities say Kuban made several Craigslist postings each week directing men to his ex-girlfriend's home for sex or to buy pornographic videos. Some men refused to leave and the woman had to call police.

According to the Star Exponent, the victim had to change her phone number after receiving up to six unwanted calls each day.

Kuban is scheduled to appear in federal court in Charlottesville on Friday for a hearing to determine he should be freed until trial.
