Yes these. Essentially anything that an unidentified user could push data to that would land me in regulatory trouble. I would want to host these things, but I don't want to become a distributor of anything that would get me a search warrant.
Lemmy instance for me as well. I have a specific community I miss from reddit that I want to replicate, I even have a domain sitting around that'd be good...I just don't want to store data coming from complete strangers. I also have zero interest in any sort of admin/moderating. So I'll just go without it and get over it lol
