GITrDONE (Great userID, by the way)
I have no idea if an an ignore feature will even be considered, much less implemented, but have seen it used in other venues and it can be a very useful tool. I too have all too much experience with disruptive posters and those who post for no reason but to invoke a response, regardless of how they need to act in order to get it.
The ignore feature allows any user to hide any other user, where you no longer see their posts. If programmed accordingly, it also allows one to view members currently on that list, and 'undo' the action if warranted.
It is a more constructive method of dealing with them than it is to respond, attack and argue, as that is exactly what they are searching for. It is nice that non-admin members try to confront this situation, but does no more than make the problem worse. I've seen it thousands of times, and I can tell you from experience that once a feature like that is added, it tends to leave those attention seeking patrons huddled in a mass by themselves, and actually helps making identification of abuse a little less challenging.
Enough, I am now bounding off of my soapbox, and wish all of you who are celebrating accordingly a wondrous Holiday season and a prosperous New Year.
