But why should this limit who the thread source can show it to? Why should you have control over showing it to (from their perspective) randos, and not the person who's being replied to?

Being able to hide it from *their* followers - what legitimate purpose does that serve?

@dave
This is why hiding content (either from blocks, lists, etc) has so many trolling edge cases.

...Which leads me to wonder: What is the reply's visibility being able to be set that supposed to do? What is the intended use case? Why can a replier or quoter be allowed to isolate someone like that? Is it hidden from moderators?
