I have the same format for my gmail account, with a second that has a middle initial, and neither account ever really gets that sort of traffic.

Literally the only time I've gotten something that was for another person is when someone else with my exact name purchased something medical and they emailed the receipt to "[email protected]". It turns out that if gmail receives an email in that format and all they find is "[email protected]", they'll go ahead and stuff it into that inbox.

I was able to track the person down, call them, explain what happened, forward the email to them, and delete it.

My name isn't super uncommon, but for whatever reason I don't get those sorts of emails.
