Misplaced priorities

If I want to sign up to any given mailing list, the first thing I have to do, after giving them my email address, is click the link in the confirmation email they send so they know that
a. I typed my email address correctly
and
b. I actually want to be subscribed to that mailing list

On the other hand, if I want to create an account on, ooh, let’s say Amazon for example, apparently all I have to do is fill in the @&!#ing form. No validation whatsoever.

In other words: I am now getting emails from Amazon India to my GMail account.

Would you like to guess how much use the first-level Amazon UK customer service representatives are at helping resolve this?
