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
pretty sure that's original (check out the text; it's white) if you don't like it, you can lighten it up with Ps or something by moving the sliders for "Levels" (see screenshot https://imgur.com/kzOBboT)
