"We're using this progressive, and what we believe unprecedented, social media tactic to warn any potential participants that this type of criminal behavior is not welcome in Prince George's County," a news release says.
Police say the photos of suspects and information will be tweeted as the sting happens.
Still, advocates are outraged by what one organization calls a "horrible decision" that could endanger the lives of these sex workers.
"I think it's terrible. It's awful," says Cyndee Clay, executive director of HIPS, a nonprofit organization that "promotes the health, rights, and dignity" of people affected by sexual exchange.
"Shaming doesn't work."
Clay says campaigns like this don't decrease prostitution or help address the issues that lead someone to become a sex worker.
