I worked at a Hospital and they put in some new spam filter software and all of sudden I started getting tons of spam email. I went to our "network guys" and mentioned this being a bit of an issue for me. Their response was for me to click the unsubscribe link at the bottom of any spam emails I had got.

So you want me to start clicking links in emails from people that I don't know who or where they came from. Are you fucking brain dead? This was apparently the recommendation by our "security guy" as well. I had to raise a huge stink about this until they finally reviewed this policy and decided it was bad. This was in the last two years as well. This wasn't some distant past where security was a little more relaxed.
