It often happens that I receive an email like this:
Hi, email@example.com --
Check this out:
This looks like my acquaintance has gotten his computer infected with malware that has harvested his email contacts.
Often this happens with people I'm only slightly acquainted with, and for whom I have no means of contact other than email. Is it reasonable to respond to this by emailing firstname.lastname@example.org with a copy of the message, saying: Hey, I think your computer got infected with malware that has harvested your email contacts? Or should I:
- not respond at all
- blacklist email from herbal-viagra.com in my spam filter
