BenStilller got hacked

For those of you who haven't heard about it on Facebook or Twitter: my Youtube account got hacked about a week ago. The person who did this changed the password and the email address. He started to put text-adverts on some of my videos. They lead you to a website that asks you to register to some online Casinos. I am not connected to these adverts in any kind. One of my videos ("Remmidemmi die ganze Nacht") got deleted by youtube because of the advertising.
I already contacted Youtube/Google several times, but they might need some weeks until I get my account back. Maybe I will never get it back.
I just wanted to let you guys know: if you see any advertising on my youtube account, I have nothing to do with it.
I am setting up a backup account right now. Further news about that soon on my website, Facebook and Twitter.
