Is it possible for personal information (that I do not provide) to be retrieved from my anonymous youtube?

[Jeff W]

I made an anonymous youtube account to prevent public (and computer savvy) people from getting my personal information (including IP address). I have real youtube accounts that I use with videos of myself, but I made this one to post comments that I do not want linked to myself personally. Is there any way that somebody could "hack" youtube to find out who made a particular account and thus retrieve their personal info? (whether they provided it or not)? Thanks in advance.
