Maybe they accidentally commented with their porn alt? Seems like the comment was deleted.

And just to add detail, because I found it confusing when I first joined Lemmy: local shows posts from all communities on your instance, and all shows posts from all instances (your instance is federated with).

I tried out different apps because of the autoloading of new posts that happens on the site. I think that might have been fixed in the update, but now I’m having issues logging into lemmy.world on the site, because if the update. I keep reminding myself it’s early days and things will get smoother soon.

I hope the Lemmy devs implement instance blocking soon as well, I’ve been playing whack-a-mole with all the porn communities, but most of them are coming from a single nsfw instance that I wish I could just block outright. I know I can disable nsfw content, but there isn’t really a distinction made between porn and other types of nsfw content, so I don’t really like disabling it all together.

As far as I can tell, that’s exactly what the block function does. I haven’t blocked any users, but at least I don’t see the blocked communities on Local or All. Maybe you are seeing communities with the same names as the ones you blocked, but from different instances?

Great and thanks for the tip!
