Why do I keep seeing magazines on /sub that I'm not subscribed to?
I usually browse under kbin.social/sub.
I noticed some posts from lemmyshitposts@lemmy.world and many others popping up in the sub-feed. The thing is, I've never subscribed to these magazines.
I even went to the magazine to check, whether I've subscribed accidentally, but I did not.
Posts from people you follow appear in your sub feed based on my observations. Doesn't matter if you subscribed to the magazine in question, I assume "following" is just subscribing to a user behind the scenes. Given a magazine is just a special user account iirc.
I haven't noticed this in my own feed yet, but it's also possible boosts of users you follow are also shown to you.
So it might be worth checking who boosted that thread in your image.
Edit: Doesn't seem to be the case, no, you're following neither the creator nor booster of the post.
Well why else would you follow them, if not to see them in your feed? I'm pretty sure that's the main use of following somebody, since it's basically like subscribing to an individual account as if you were subscribing to a community.
Have a look if you don't have an accidental subscription to kbin.social.
I had a similar problem. That seems to be a connection point for federated posts and makes all of them appear in your subscribed feed. It does not appear on your magazine list.
specifically the one in the picture is under the domain programming.dev so I would check there. For instance I just checked /d/programming.dev and I see plenty of 196 blahaj posts listed
