when I visit a church, they ask everyone for a little money so they can keep the lights on and do interesting things once in a while. nobody expects the church to KYC everyone who puts a dollar in the collection plate. why should that be any different if the meeting takes place on a website about something other than religion? I donate cryptocurrency to forums and microblogging services to help them keep the lights on. we should be treated the same even if we don't believe in god. the owner does not need to ask for permission from anybody or depend on an intermediary to accept the money and they do not need my information. if you don't see why this is of benefit to someone then I suggest you try to operate a forum and go through the trouble to make ends meet.
(Almost) everybody do it with PayPal, Patreon, etc.
I understand that you feel uneasy to theoretically depend on these companies, even if in practice you encounter no real difficulty.
Your fear is unnecessary... unless you do things really frown upon. Even porn and sex services are successfully using some of the online services I quoted above.
For hitmen and substances I don't really know, but those are really frown upon.
