The one that catches a lot of attention is called Aegis and you can slap that into your search bar and see the labeler there. These are all USER RUN except for I think one labeler/list and are completely optional, mostly used by users who want to curate and protect their viewing experience

The official one is literally called Bluesky Official and contains sexual content, spam, rude and other labels. I don’t fuck around with lists because I’m a lazy ass motherfucker
