My intuition (usually wrong) is that Rentmen is toast and MassuerFinder may stand a chance as last one standing. Maybe.
The law applies to companies like Google as well as RM and they are going to get more aggressive in blocking. Maybe providers like Comcast too. But I thought this would happen sooner and if a test case gets before the courts first the law could be held up awaiting appeal before much damage is done. (At least parts will be overturned). I don't think Google etc is having an easy time making filters that don't block a hell of a lot of stuff like Tumbler, Twitter, OnlyFans and Grindr.
If the worst happens I see MassuerFinder maybe surviving and guys going into Grindr looking for "bodybuilder sponsors", "generous" guys, "daddies" , etc. But it will hurt escorts' business a lot.
