At last, Furaffinity introduces a long waited blocklist (basically a blacklist like on e621) feature! A boon for fetish artists like yours truly~
You can add unwanted tags into a blocklist in your Profile Info or right from submission tags (there will be a yellow square with +, clicking which will instantly add a tag to your blocklist). This would allow you to never see a content you don't like, if it's tagged properly c:

Some tags I usually use for my fetish related uploads:
scat
feces
poop
fart
flatulence
gas
ws
watersports
urine
piss

Also consider these ones for blocking if you don't like the topics, as they might eventually appear in my gallery:
vomit
emeto
vore
enema

Hope this feature will make our beloved platform even more comfortable space for all of us,
Thanks for attention ^^
