@evan no, not really.
I'm just annoyed that the fediverse is treating any object as belonging to a global namespace when that's simply not true.
What I do do is to give tags an actual HTML representation, where there's details and what not. (See something like https://releases.bruta.link/tags/New )
And I plan to use them this way in the different instances of the brutalinks link aggregator. On it local tags can be used to differentiate between actor roles on each instance: moderators as an example.
