My work email has an incredibly deft spam filter, so it's very rare that spam actually gets to me.
Lately, I've noticed that someone out there is spoofing my actual work email address to make it appear as though I'm emailing myself.
Obviously, I'm not stupid enough to fall for this, so I ignore and delete all of the emails.
Unfortunately, this only serves to piss off the spammer, who has resorted to hostile subject lines to get my attention.
They have the added effect of making it seem as though I am emailing myself and getting annoyed when I don't reply - to myself.
