upvote because showerthought, though I'm not sure if it's true. I'm only subscribed to !196@lemmy.blahaj.zone but browse c/all and block communities I don't want to see.

Also off topic, but oh my God why are there so many anime subs. It's not really for me and I'd rather see other stuff, so I blocked a few, and they kept coming, and coming... and coming. Like look at how long the list is now 😭

(no hate if you are into anime subs, it's just not for me. Except miku, I like miku ♥️)

I don't think so but you can definitely determine which communities someone has commented on by where they comment.

I’m not subscribed here and yet I comment

Yea i browse new and all, and comment in places not subbed to.

What about people surfing all?

not even kind of. there are a ton of lurkers who dont comment at all

Not really. You don't have to sub to comment and I doubt most people sub. I don't.
