Fediverse

Throwaways / burner accounts remain a thing that are available for both positive and negative use cases.

In case you're not aware, all your activity via the ActivityPub protocol is already public - it's just that the details are hidden by some front ends. It is already possible for anyone motivated to check your post from a federated instance that displays full vote details, or to host their own instance and receive the raw voting information from places they're federated with.

Yes, you can have communities with higher moderation standards, Beehaw is a great example -- but those are local moderation standards, it does not stop the general public from seeing what's going on as onlookers.

IMO it's no different than most message boards in the earlier days of the Internet. You are pseudonymous, not anonymous, and when you consistently participate on an account, that identity is going to develop a reputation based on how you participate. Upvotes and downvotes just cut down on the kind of low-effort "this", "love this post", "fukkk u omg" replies that would add noise to threads in those days.
