Memoirs from the old web: IE's crazy content rating system
The most interesting thing for me as an European is looking at the difference in levels between sex and violence according to RSACi. Look at level 1 for instance: on one side we have passionate kisses (with tongue I guess?) and on the other, killing animals already. At Level 2 we are already killing people, while at level 2 clothed sexual touching. Beating someone? Bah, not even contemplated.
