i guess that begs the question of why specifically does that kind of thing bother you and how exactly are you defining/observing the problem
i feel like the vast majority of people in fandoms tend to keep their stuff with people they know they can share it with (which includes communities that are generally receptive to that interest), since that seems logically like what people would assume. i hear the complaint that obsessive fandom members annoyingly spam their interest all over the place, but i've genuinely never seen a living example that wasn't intentional or just a case of exceptionally poor personality. assuming the problem is being defined as an annoying, blatant, and obnoxious insertion of the subject matter into completely irrelevant discussions, and not a passive expression of interest like an avatar or a passing reference when appropriate
probably worth noting that i'm speaking as someone who is undeniably fandom trash so i guess i feel as though i'm on the defensive here
