This is exactly what the Fediverse is for; the sex industry tends to be quite aggressive about adopting new technologies and I expect they’ll also do so here. (maybe even an entire alternative cloud of NSFW-friendly instances - people tend to be happy to have separate user accounts for porn consumption anyway)
Switter was the third biggest Mastodon instance when it was open. It was specifically set up by, and to be Sex Worker freindly.
Guess what happened… Laws passed in Australia that made running the instance troublesome, and the hosts couldn’t afford to constantly legally defend themselves, so it closed down.Try and find an instance that welcomes Sex Workers and allows them to advertise. Last time I checked there just isn’t one. I’m a photographer that works with Sex Workers, and from what I have seen they will stick with twitter until it is offline, then probably head to bluesky.
OK, but isn’t one of the benefits of federation the ability to base instances in whatever jurisdiction you like? There are plenty of countries where hosting an instance for sex workers is NBD.
