They probably got demonetized on most of them... a few blocks and maybe even some claims. Three strikes and you're out (I believe)... they can't risk losing a whole channel because of a few hateful idiots who own publishing rights.
@@bubbafug00gle51 the videos disappeared sometime after the A.V. Club was moved from a platform that The Onion had originally created to one run by Gawker, which subsequently led to a lot of their content disappearing (e.g. user comments). Also they completely revamped the entire A.V. Undercover series (which is why it looked so different in later series and imo also was not as good as the earlier seasons). Could be either that they did not want to renew the rights for the music used in the old series or just did not think that it fit their brand identity as a whole.
