I also am on kbin.social, and I do not even have the “Hide NSFW content” turned on, and I almost never see it. I haven’t had to block anything (maybe once?), and in the <1/1000 chance it pops up, it is blurred by default.

It can randomly show up in the Active People area though.

Lemmy/Kbin is a wild, uncharted frontier, still alpha version software and very much in active development, it does not just “take care of people” like Reddit and Twitter did - you may want to not browse it at work then. Also, even if you successfully blocked every single porn magazine, as you see a new one could come up and blow up your entire All feed at any point in time -> that approach was never going to be 100% successful.

So it may be worth the pain of switching to Kbin, b/c that will work? Note that you will lose everything that way - account migration is something promised but not yet implemented iirc - but you can still see all of the communities you subscribed to before, from the new server (you will just have to subscribe to all of them again, plus block all the others, like I unsub from every foreign-language one that I see).
