I have a commonish firstlast@gmail account and frequently receive what is the obvious result of people in various parts of the country incorrectly providing my email to apply for jobs, order pizzas, and use other services.

It is absolutely common for users to supply the incorrect username/email.

This is why it is common practice to require the user to enter their email address twice in forms.

Thank heavens we never invented copy and paste, would certainly make this more of an issue.

Apparently the set of users who don't know how to type their own email and the set who know how to use copy/paste are non-overlapping.
