>>What is the difference between some on the hub jumping all over a poster for one post, about one stock, on 4 or 5 boards posting once, compared to one poster with 40 or more posts about one stock on the same board?
From my perspective, it's a matter of practicality. A moderator can control repetitive spam on a single board if it it excessively disruptive to the dialog on that board and can escalate to Matt if necessary. One of the most common complaints about spammers is that they often hit the most popular boards, and users who BoardMark those same boards are alerted to new posts, only to find they are all the same post spammed to multiple boards. The multiple-board spammers are more easily dealt with by admins, while disruptive posters in individual boards are more practically dealt with by the moderators.
In any event, it is not an exact science since there are any number of subjective factors to be considered. As is the case with most similar issues, any expectation for total uniformity in dealing with them is a case of mismanaged expectations.
