The EFF has sued to overturn the censorship law, FOSTA.

A similar wave of repression is campaigning for such a law in the UK.

The real goal of such campaigns is to try to repress prostitution. Thus, what they really do is harm sex workers in general, rather than protect them from enslavement.

It is possible to act against enslavement without creating repression, but that requires licensing and monitoring the web sites and brothels, as well as ending prohibition of brothels. The monitoring will cost money.
