I almost never watch "shorts" but my suggestions for it seem to have an...uhhh...adult theme. I don't watch any such thing with YouTube. Does everyone see garbage like this?
Mine shows 90% videos from channels I've either subscribed to or at least watched before, and 10% random pop culture stuff.
Then again, I don't actually use YouTube very much, and if I come across a video on Lemmy or wherever I never open it with a logged-in browser. Maybe I've inadvertently gamed the system.
