I'm not going to link my expansive blacklist, but I have 3 key ones that I ToS (Tag on Sight) or otherwise avoid at all costs:

3D Animated, barring a couple Judy Hopps and H0rs3's, I dislike 3d animations. Expressionless and lifeless, or uncanny valley, take your pick.

Cuntboy, because of the stigma that comes from the arguments. Might as well not drown myself in the miasma of negativity, but I do not have disdain with any of the characters.

Dakimakura_design, because it's CTRL+C, CTRL+V. I will gladly upvote and/or favorite the individuals, but when it's back to back in the same image I only see it as image bloat. If multiple_images counted them, I'd edit this so I can see it no problem, but until then I don't want to see 99 posts of the same thing.
