SJW is 16+ according to the legal section, I’m on the SJW Matrix chat and I can confirm with the admins if there’s interest.

We’re defederated from Beehaw so if there’s any active users from there you’d lose them moving to SJW, and vice versa.

Edit: .zip seems to be 18+ per their TOS, Sopuli is 16+, world is 18+, and Beehaw can refederate >:(

Edit2: Sopuli and Beehaw are still federated, Sopuli might be the right choice, but I know quite a few .ee comms are looking at piefed and they’ve got some nice migration tools but I don’t know much about the piefed instances beyond seeing their users and communities once in a while.
