You should be able to have a block system on discourse, where you can’t see their info like view your profile, they can’t see yours
Sort of, there’s also an Ignore option as of Discourse 2.3.
Twitter style block goes further, it is like a forced two-way ignore, meaning your content is now hidden from the other person as well. It does not have a lot of precedent in discussion software to my knowledge.
That’s what I mean by blocking. Lol I couldn’t think of an actual example, thanks.
