According to BleepingComputer they are using this policy to report fake infringements. Once a channel has received two fake strikes they contact the creator and demand money via PayPal or Bitcoin. If the demand is not met, they will issue a third strike, whereas if the ransom is payed the scammers promise to contact YouTube to get the fake infringements removed.

Now if you think that this issue should be easy to resolve you are only half right: While YouTube is pretty fast when it comes to distribute strikes it takes them way longer to remove them.
In the end things worked out well for the YouTuber and the account which reported the fake infringements was deleted – but what if the scammers had reacted faster and had delivered a tighter timeline? One can only hope that YouTube will create a mechanism that protects content creators from cybercriminals like that.
