Sleazy classified site Backpage.com was shut down Friday after the FBI raided the home of its co-founder, according to new reports.

Agents raided ex-owner Michael Lacey’s home, according to a local CBS affiliate — while users are sharing screenshots of a message saying it has been “seized” by the feds.

“backpage.com and affiliated websites have been seized as part of an enforcement action by the Federal Bureau of Investigation, the U.S. Postal Inspection Service, and the Internal Revenue Service Criminal Investigation Division,” says the message shared by numerous sex workers across the US and Canada.

“Backpage has just been seized by the federal government and taken down. This is terrifying,” tweeted porn star Taste the Moon alongside the screengrab.

Others worried they won’t get money back from ads they’ve placed on the site, a popular marketplace for sex.

“So how much money do you think #backpage just stole from us? Thank you for getting rich off of us then kicking us while we’re down by changing the way we pay for ads, and pocketing our current balance,” wrote Miss Marla Moon.

Backpage has long been in the crosshairs of lawmakers, law enforcement and activist groups, who say its listings enable sex trafficking.

The Department of Justice and FBI didn’t immediately return a request for comment.
