LGTM!

I wonder how many of these throttles we actually need. Sometimes I refresh or do other actions in quick succession and they get throttled.

I added the throttling in initially to prevent spamming requests to the instance servers. Since then, I've just been adding them out of habit. I think we can evaluate these things on a case-by-case basis.

For example, you may want to mark a lot of messages as read from your inbox, so it makes sense to remove throttling there. Similarly, you may want to upvote or save a lot of posts within a short timeframe. However, refreshing posts and fetching for more content doesn't need to happen very quickly!

That makes total sense. However I think it would be hard for a user to overload an instance via manual actions from a client app. I think servers get overloaded when there are automated API requests in the thousands+ per second. If I can press the refresh button on my phone so fast that the server starts having trouble, then it's really gonna be in trouble when it has lots of users. 😆 But fair enough, no need to overburden them more than necessary. Maybe we can look at eliminating some and lowering others.

Also you mentioned refresh, which ironically is what I often do that gets throttled by the app. 😆
