One of the most acute problems with centralized platforms is the need to develop one-size-fits-all moderation policies for billions of users. Decentralizing social platforms places the power to determine moderation policies in the hands of users or communities.
Servers in Matrix have terms of use that users agree to when they join. Rooms may have moderators who can remove people from individual rooms.
### Mastodon
Each server admin can create their own moderation rules as well as a theme for their server. Their TOS may include rules about whether data can leave the server, etc. Users choose which server to join, opting into the moderation policy, theme, and TOS they prefer.
