I strongly believe that if you want to receive email from a site you would enter a valid email address.
You're missing my point. When sites don't require people to respond to registration confirmation emails, I can sign up using your email address, resulting in you getting a flood of spam.
This battle was fought in the early years of the spam war -- companies would send out spam and claim that people had asked to receive the email, and when anyone complained that they hadn't, the spammers would just say "oh, someone else must have signed you up".

To be fair, if they are going to be sending spam I dont think they care if you validate your email address. Enter someone elses address and as long as it doesn't get a bounce back, its valid in their eyes.
