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 snuff) should give you a warning before you even see anything, if they don't you disabled it
For the ones who dislike the cock vore/anal vore/unbirth tagging, it's being discussed HERE so go there if you really want to try to change it
