I had been having this issue for years, but it wasn't spam; it was just some stranger who got my email mixed up. I kept emailing him, asking him to stop, but he insisted he wasn't sending me requests. I would spam him and all his contacts back, continually proposing new dates and times. I blocked him and tried everything, but nothing worked. I just realized, thanks to this article, that he finally stopped, LOL. Now, if only you could figure out how to remove all the spammers who attached their emails as backups to mine. I would appreciate that! I receive requests in different languages from people who have attached their email to mine as their backup, but it's mostly spam. Most of the time, I can't even read the email to disconnect it. If you don't disconnect it on that first email, it's connected forever somehow.
