A final word.
I am going to be brutally honest for transparency purposes.
While it may seems like the staff have been doing nothing about this, I assure each and every forumite that this is not the case. Discussions have been ongoing for a long time.
One point of the discussion was that this type of thread relating to this particular subject with these particular participants keeps popping up and the staff are tired of it. So this thread was left open for them to vent, insult, swear at, degrade and attack each other so that the staff now have a basis on which to hand out warning points that add up on the warning level of each profile.
Should the warning level reach 100% on a profile, the account is banned automatically. Warning points are handed out per rule transgression, per post, per member (ie, not only one warning for the entire escapade).
Staff will now action the warnings to all involved and any opposing thoughts may be directed to the moderators.
