You can filter most of it out by adding the appropriate words to your filters. Do a search, then with the results displayed open you filters and add any keywords you see in the search you find offensive!

Next time these sort of results will not show up.

Eventually you will eliminate most of what you do not want to see.


PS just coz you dont like it, does not mean someone else does not, stuff like porn is one of the reasons p2p is managing to survive the US legal system, it shows it has a alternate use apart from stealing hollywood movies and music. (Whilst most porn is probably copyright, the industry is not phobic about chasing down file sharers like the MPAA, and the "American bibble belt run judges" dont seem all that inclined to worry about it either)
