(bolding mine) Sorry, I have believed things that were posted here or PM'd to me. Unfortunately, I learned the hard way that one of the most prolific posters was untrustworthy. I followed the advice I was given and ended up having a supervisor take copies of my ID/BP and the TSO's 'helpful' PM and giving me a lecture on how stupid I was to believe that just because someone self-identified as a TSO and posted as such, it was not necessarily the case. In fact, he told me, it was a likely scenario for someone with bad intentions to try to test the system by taking advantage of my naive trust.

He kept the PM for the 'report' he was making on the incident.
