Also, I don't think we need more regulations or rules. We simply need to define the the market better. For instance, the forum should respect people's choice to delete any notes. But the forum also allows re-posting (转贴). Hence, if anyone who deletes his/her notes on positioning now knows that any deletion will be re-posted by the operator, then no one will bother deleting in the first place. And when people initially post their information, they will also be more careful. Win-win situation and the market will do its job. All we need is a commitment by the operator without changing the structure of the market or the existing rules.
