I don't have something like that, but every time this kind of question is asked, City of God (2002) always comes to mind.

Did you uncheck "Show Read Posts" in the settings?

I don't see any problem here. Lemmy's RSS feed result will still be the same even if you have an account or not. The 2nd OP has only title in it, and your RSS client was probably trying to fetch the nonexistent full content of the post.

Not a problem to me. It's their instance, they can do what they want with it. The problem is people coming in here and telling them what to do and what should be right or wrong.

Hey, that's me, lol. It's probably a bug in your client. I'm using Jerboa and everything's fine on my end.

No publicity is bad publicity, so they're actually promoting Lemmy for free.
