After SESTA-FOSTA, the pages hosting those ads folded, as they couldn't comply with the new rules. Many full-service workers are now walking the streets again and have to have sex in their clients' cars. It's obvious that this makes them much more vulnurable.
It even goes further: Banks will close your account if they think your business has something to do with "sex", even if what you do is legal. If they feel you might be a risk, they freeze your account.
This law has hurt many sex workers, often people already at the very bottom of society. On the other hand, it's unclear how many lives it saved from sexual exploitation.
Sex workers are vulnerable, and many women are being abused. But the way this law was enacted, I can't help but think that pushing sex work further into illegality was a desired side-effect.
