I wanted to start a community, including a matrix server for chatting, but public signups cause some “undesirables” to sign up and when I finally figured out what rooms they joined and what they were posting (unencrypted) I had to nope out of the whole project over night. They seem to scan the federated network for public instances with open registrations and then do shit like this. It’s a shame but the only community effort I could see myself doing in the future would need to be friend-to-friend networks or invite only or something like that…
