For a long time, I've wondered why youtube and others either don't ban posting illegal acts OR at least force you to sit through a 15 second long legal disclaimer banner on each one.
One auto forum I used to frequent when I was into all that took a stand around the year 2010 or so on all this finally after some high profile crashes/deaths. No more posting illegal street racing videos, period. Only dyno's or track videos. Offense was a ban as you read the disclaimer in the user waiver and also due to how bad spreading the videos was causing increased bad behaviors.
