All I see is porn, every kind imagineable it seems.
And most isn't marked as Nsfw. This make this site very unappealing to me as I can't just scroll info in public without looking like a creep.
I'm not against porn in general, it's just too much of it.
Are you in the "All" view? You could go to your "Subscribed" view and then you'll only see content from the communities you have deliberately chosen to follow.
Another (somewhat tedious) option is to go to the sidebar of the community of the offending posts and click "block community". That should hide that entire community from any of your views.
As people have said, check your settings and make sure you've turned off nsfw. I see zero porn anywhere, including when searching All. If you aren't using one of the Lemmy apps, too, I would look into those - that might make a difference as well since you can kinds of fine tune settings on some.
