npub10q397r7jx97c6m8tnluze66ua7mw8y5tf8qhxjs234mellrmyfdqzykgta (npub10q3…kgta) I see fediblock used for individual accounts as well, but I don’t really understand the norms.
Also you can silence a whole instance for yourself as an individual if eg your mods won’t do it.
Block is the trickiest bc I’d like it to mean “I don’t want this person to be able to interact with *me* or see me at all,” but the degree to which that works…depends. So when some chump on a VERY blocked instance tried to troll me, I couldn’t see it, but other people could.
