Yes, and that may warrant a sit-down to explain why others are upset. To have our big boss ignore our own rules strikes me as gross misconduct. Like I said, it would be an Internal Affairs issue. I'm hoping that we can just learn and move on, but I may still say something to Vixy to prevent this from happening again.
Really, if you have the power to edit the hell out of another's post, use that power. You generally have a good reason to do so if the post displays something the crosses the line. I went through and removed a number of things and I may go back and remove even more. Not a second thought, either, using myself as a gauge for what's permissible.
