Problem I have is I got my lastname@gmail.com as my email address. Many times when people with my same last name they’ll type firstname<space>lastname@gmail.com for their email address. And guess who gets signed up?

At first I unsubscribed, replied back to emails that were meant for someone else, etc. But the number of things to unsubscribe from unmanageable and it gets to be too much of a chore.
