The situation is clearly illustrated by post #20297 over there. I TOS'ed it as it was against another poster, not about the stock under discussion. Mods have been admonished and threatened by Admin for leaving such things behind. In this case, on that board, it would seem the criteria for such a removal are in some way different.
Good.
The more things like this they leave behind, the more counts will be added to the coming actions.
