"Because copyright law can be complicated, education is critical to ensure that our users understand the rules and continue to play them. That's why we're releasing a new tutorial on copyright and a redesigned copyright help center. We're also making two changes to our copyright process to be sure that our  users understand the rules, and that users who abide by those rules can remain active on the site." explains Justin Green, YouTube's highly trained monkey. 

"We've found that in some cases, a one-size-fits-all suspension rule doesn't always lead to the right result. Consider, for example, a long-tim YouTube user who received two copyright notifications four years ago but who's uploaded thousands of legitimate videos since then without a further copyright infringement. Until now, the four-year-old notifications would have stayed with the user forever despite a solid track record of good behavior, creating the risk that one new notification - possible even a fraudulent notification - would result in the suspension of the account. We don't think that's reasonable. So, today we'll begin removing copyright strikes from user's accounts in certain limited circumstances, contingent upon the successful completion of YouTube Copyright School, as well as a sold demonstrated record of good behavior over time."
