I've got a common enough name that hits one of my Gmail accounts. I reply ALL back, and tell them I'm not the person that they are looking for. Although for some issues, this doesn't work. Juniper Card Services. I've emailed, I've talked to them on the phone, I've marked them as spam. I was able to figure out one guy's real email (he was looking for a new car) who lived in Hong Kong. Another guy in West Virginia was sending me stuff about used cars, and the sender was pissed that I wasn't responding. I told him where I lived, NOT in WV, and that his emails were going to the wrong place. Frat brothers have sent me crap. I've gotten a ton of personal emails.
Luckily for me, I don't use this email address as my regular address. But if I did, I would be doing password resets just to lock those jokers out of their accounts.
And I have deja vu, didn't we discuss this previously on
