I want to point out that the only way someone could have this information is if they are conducting de-facto surveillance on the entire forum on an ongoing basis. There is no other way to detect the start/end dates of signature campaign like this, nor the 'users', 'posts', and 'deleted' columns. This is further evidence that all posts made by anyone is being collected (surveilled). This is evidence that this person has a database of every post in the forum.
