#crazyidea : a Mastodon instance, where every new account is a random generated fantasy RPG character, and you'd be locked out of editing your name, pic and bio; all of which would comprise your charactersheet.

Bots would administer loot/magic items/weapons and other both would pop up to be random encounters or dungeon crawls or even story lines run by admin GMs.
MUD meet social web.
