You could be right but I was actually wondering the opposite. Whether multiple people are sharing IDs. There was a post yesterday from GM that was very long and articulate. It was disgusting, and I had it removed, but it was unlike the usual short dumb posts. A new potential stockholder will have no way of knowing the difference.
I was new once, I read every post on both boards. I am glad I had other DD or I would have never bought this stock.
