That is a spam email They are hoping that their emails reach someone who does have a You Tube account and are foolish enough to follow the link int the email - thus with the spammers ending up with the login details of their victim.
I get them as well - I don't have a You Tube account linked to my email address - I do have a work You Tube account.
The golden rule is NEVER click on a link in an email to take you to your account with a bank or other website. ALWAYS go to your bank or the other website directly and log in that way.
Do you have a Google email account as the two are linked. If not and you don't have a Youtube account and therefore haven't uploaded a video it's safe to assume the email is spam innit ;-p
Thanks guys I'll just delete it..............I don't have a Google mail account. I was just worried that somehow, someone had set up an account with my details. I had to change my passwords last year as someone hacked my FB account.
