Sujet : YouTube hackings

Most of you will know about the PSN hackings that happened a few months ago, causing the entire network to be shut down for ages.
Well now it seems there are hackers going into YouTube…. Okay, so it's not quite as bad as the PSN's hacking, no one's credit card details or money are at risk. What's being done this time is these hackers are hacking into individual YouTube accounts and posting inappropriate videos on people's channels, then the YouTube moderators come around and delete the accounts for posting videos of a bad nature.
So far, accounts such as the official Sesame Steer channel and the extremely popular Fred have been deleted. Since then, YouTube staff have realised that there are hackings going on, and Fred and Sesame Street's channels have been restored, however no videos are available. I am worried this could become a serious problem as there is no certainty that all hacked accounts will be restored…
