I'm sure a bunch of people would join. They need:
1. to know about it, you have to spread your message;
2. information what they are signing up for;
3. assurances, about the legality, also that they will be safe, and can safely return, basically that they will possess the ability to make decisions over their own fate;
4. and related to the above: a way of safe return - in case it doesn't play out as they imagined.
From the top of my head. You can't do this on IBs anonymously.
For example we do stuff with Bernds/anons online, make things, or play, and I would do more complex things, with more public exposure, more considerable projects (well if my time would allow...), but irl it is kinda different. For example for a meet up with a Bernd, I would plan so that I could rely on myself if necessary and return to home if something goes sideways.
