1. You can blacklist uploaders who mainly upload stuff you don't like (in settings) 2. You now can hide tags you dislike, and watch tags you like (configure it in "my tags") 3. Galleries with some tags (like guro and scat) should give you a warning before you even see anything, if they don't you disabled it
Looks to me like a case of, "If I can't have you, I'll make sure that none of the other girls can!"
Also, a minor nitpick: Shampoo has, to my knowledge, never referred to Ranma as "Ranma-chan" -- not even when he is in his female form. She usually calls him "Ranma" or variations of the term "husband" or "beloved".
