You can't be sure. As I said before, the post that began this discussion could have been made by a shorter. But if so he was also a shorter who had news of the management changes occurring and wanted to disseminate that news in a way that caused the SP to react quickly in order to profit. However that news was still very relevant. So, exactly like when using a service like HotCopper, its up to the user to pick up on the relevant information and filter out the noise. Even those deliberately trying to inflate or hurt share prices can still carry valuable information (however rarely).
