While I'm glad that furries have a nice space where they can (hopefully) not be harassed, I decided I could use a bit less furry porn in my life. On kbin (on mobile, in the PWA), you can block a domain by searching for it (I think it was yiffit.net, but I can't remember), then click the kbin logo at the top right, then scroll down to where you see /d/yiffit.net, then click the little block icon. I'm sure Lemmy has the same capability, but I don't know how to do it. With that, the new feed has a lot less porn lol.
EDIT: it was yiffit.net, not furryit.net
EDIT: well, that wasn't very effective. It took 1 page to find more lol. It gives me... somewhat fond memories of browsing /r/all, sorted by new.
