Here there’s a different kind of self-censorship. Anything you do (including your upvotes) gets propagated out using the ActivityPub protocol to all instances that are subscribed to that community. So in theory, admins on different instances can tell what you’re upvoting. A bad acting admin could stalk you here in a way that a mod never could on reddit - because mods couldn’t look at your upvote history.

The good news is that they cannot delete or modify your content on other instances (only their own), so they’ll never pull a spez and edit someone else’s comment globally. And, bad acting admins will simply get defederated, so we should be self-policing (in theory).
