Well the banter aspect is something you could raise if you were appointed to the Habbox Council, which I personally feel has a great chance of happening.
With regards to disagreements, I do believe that members should be allowed to disagree with each other. However, as you say, the line between argument and disagreement is so fine, that friendly disagreements are often mistaken for full blown arguments and the thread is closed.
I try to overcome this, in this forum in particular, by choosing the close a thread if it meets any of the following criteria:
- Disagreement becomes so far gone that the original point of the thread is no longer being discussed
- Genuine disagreement results in mindless insults being thrown at different members/staff
- The disagreement is filtering in from a different thread, and the appropriate thread is not being used
As I'm sure you'll appreciate as a forum super mod, every moderator has their own style, and interprets the rules in different ways. Where one moderator can see an argument, another may see an interesting discussion. Unfortunately I doubt this problem could be overcome, unless we install some sort of hack which moderates the forums without need for human action; which of course is not possible :P.
