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
Please note that a gallery should never be tagged female:"futanari" and female:"females only" at the same time. It's right there, in the tag definition.
