BREAKING: EFF has filed a lawsuit asking the federal court to declare FOSTA unconstitutional. https://t.co/84U1Kbi4SW — EFF (@EFF) June 28, 2018

"Although the law was passed by Congress for the worthy purpose of fighting sex trafficking, its broad language makes criminal of those who advocate for and provide resources to adult, consensual sex workers and actually hinders efforts to prosecute sex traffickers and aid victims," the EFF said in a statement. In their lawsuit, the plaintiffs note, "The law erroneously conflates all sex work with trafficking. By employing expansive and undefined terms to regulate online speech, backed by the threat of heavy criminal penalties and civil liability, FOSTA casts a pall over any online communication with even remote connections to sexual relations. It has impeded efforts to prevent trafficking and rescue victims, and has only made all forms of sex work more dangerous."

Two plaintiffs, Human Rights Watch and the Woodhull Freedom Foundation, advocate for sex workers, but FOSTA and its broad language has both concerned they could be prosecuted for "facilitating" sex work. There's also concern regarding Woodhull Freedom Foundation's annual Sexual Freedom Summit, set to take place in early August, and whether promotion of it violates FOSTA. Jesse Maley, another plaintiff, has similar fears, as she's the co-founder of a website that helps sex workers find organizations and services they can trust.

Massage therapist Eric Koszyk also joined the lawsuit, claiming that when Craiglist shut down its Therapeutics Services section because of FOSTA, he lost his main method of advertisement, causing harm to his business. The Internet Archive is suing as well, citing concerns that FOSTA will cause it to become "subject to federal criminal, state criminal and civil liability" since some third-party content on its site "could be construed as promoting or facilitating prostitution, or assisting, supporting or facilitating sex trafficking."

The plaintiffs are seeking an injunction by August 1st so that Woodhull can run its summit without fear of prosecution. They're also seeking to have FOSTA declared unconstitutional under the First and Fifth Amendments.
