I'd like to make a complaint about the World Of Tanks ad that appears in the square ad box in the top right corner of YT's home page. I have few issues with ads on websites, but it is ridiculous to have an ad that has sound on a site that has it's own sound source (user videos). There have been countless times where I've been playing a video in a new tab and all of a sudden, World Of Tanks starts up with an ad.
