Some information:

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 guro and scat should give you an warning before opening, unless you disabled it. (delete the "nw" cookie to enable it again)
