Mastodon and the Fediverse

Mastodon is a fundamentally different platform than Twitter it has different affordances, and those affordances results in different communities forming by means of the platform. Unlike on Twitter one can use the affordances of the platform to make present a consistent identity across the entire website on Mastodon. If a user signs up for multiple instances, that user will appear differently within those different instances but on the basis of how a given instance structures the use of its affordances. So any kind of harassment must be articulated differently on Mastodon because there are certain content guidelines and moderation policies which tend to act as social norms on Mastodon itself.
