I've previously had trolls demunge my headers (when I used to post how to
demunge & contact me) & post inflammatory messages on multiple groups under
my real name before, with a Google search finding them posted on groups I
never even visited. It's just a bit of self-protection. Likewise, my wife's
real e-mail account is getting bounce messages where spammers are sending
crap out using her name to non-working addresses and the recipient
mailer-daemon bounces the spam back to her.
