As it stands, scaling a Mastodon instance is hard, as the operators need to form a moderation team with 24/7 availability and good reaction times, learn about all the specific vectors for abuse and common issues, design guidelines and more.«
Their problem is "scaling". Self-inflicted pain from running behemoth servers that are counter to the core idea of the Fediverse, and from deliberately tilting the Mastodon "joining" process so that their own behemoth keeps growing.
