Why are most of the furry images not tagged furry? When I take it out of my search, it's still at least 90% furry :V

Because the bot takes 'em from furry site. Which they wouldn't tag as furry since no shit.

Because people are bad at tagging lol

They do however tag "antho" and "feral"...so if you blacklist both of those it'll cut down the furry images you see by a lot.

knot, canine, paws, there is a few typically furry related tags that can be blacklisted instead,
