So true. I had to defend a guy who worked for me some years ago on this type of shit. We had a first go round where this gal who was a contractor to us (friend of the VP of Marketing) filed a complaint because the guy had a lewd password. He did have a poor choice of passwords (EatMe69). The gal figured out what his password was by watching his fingers as he typed it . He was typing it on her machine beause he was trying to get her connected to our network on her machine, and was connecting to his account for a test. A bunch of asterisks on the screen were sufficient for her to feel harrassed. And our evil bitch HR VP bought into it. She wanted a Harrassment case to set an example, and my guy was a convenient target.
After I spent a week reviewing the facts with everyone up to and including the CEO, I got that complaint dismissed and gave him instructions that if he ever came into contact with her again, and anything went sideways, to come find me. So in a few days, he did just that, and she filed another complaint for him "making her feel uncomfortable for not talking to her" as she was ranting at him in front of witnesses.
Against the wishes of our HR department, I pulled her behind closed doors, and explained to her that she was dealing with a geek, for whom she was one intimidating bitch, and that I had told him that if he didn't feel emotionally equipped for the discussion to come find me. I pointed out that she was borderline on the edge of harrassing the handicapped, and asked if we couldn't just talk a bit. She actually broke down and started crying, indicating to me that there were exterior issues contributing to her mindset. After our conversation, she backed off, and my guy kept his job.
