I have my not-so-common name as my gmail address and I still get a ton of crap. The most frustrating is from a power company in Ohio that sends me billing statements every month. I contacted them to ask them to stop emailing me because I'm not the intended recipient. They said they can't stop emailing me because only the account holder is allowed to change the email preferences. Apparently my only recourse is to reset the password on the account and claim it as my own... for the last few years I've just been deleting the monthly emails. I also get fun things like family photos from people I've never met before
