What I'd like to see is when someone initially jumps onto a forum and begins with "exspurt" reporting is that they identify themselves so readers can judge whether to believe or not them and then decide to respond or not respond.
Not long ago we went through almost the same exercise when UL hired a new women's basketball coach. In that case, knowing the source helped explain a lot about what was posted.
