So all of these federated mastodon instances are neat, but I'm not seeing anyone making up interesting weird rule sets yet.

It seems like if we're gonna to build a galaxy, our planets should have cultures, right?

I want instances where you're not allowed to use the letter p. Where you can only use a different subset of unicode every day. Where you can only post from certain geographic locations or while going certain speeds.

Basically, I want oulipo mastodon.
