> I was getting some dude's email for about 7 years. Started with newsletters and discussion threads for a journalism guild and a teacher's union. I found that amusing and left it, but one day emailed whoever was in charge and let them know I'm not the intended recipient. Stopped for a while and then it started again and I ignored it.

I had a similar experience, funnily enough golf course memberships too. Doing minimal OSI work on the numerous emails I found the guy on facebook and friended him (accepted due to same surname I assume). I remember saying something like:

"Hi, I noticed you just signed up for an Epic Games account, and you happened to use my email address <lastname>@gmail. Would you mind not doing that, please?"

He responded that I was a creep and that it was his email, and proceeded to block me. I mean he might've been right on the former, but patently wrong on the latter.
