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.
