The particulars of the most recent incidents aren't particularly important. What matters is chat is causing far too many problems. How do we address this issue in a way that keeps as many people as happy as possible?
The things that seem to cause trouble are, in my opinion, as follows (and I myself have been guilty of all of these things at various points):
Contentious political and social issues - e.g., gun control, reproductive rights, occasionally party politics, and in a rare instance or two, race relations. By far the biggest problem in Mos Eisley, never productive, always provoking heated debate, and frequently intense, if usually short-lived, animosity.
Suspensions: This has already been covered in a post by Pureferret, and doesn't require additional explanation here.
Profanity/obscenity - there have actually been relatively few flags for this in the past few weeks, but it still happens from time to time.
We elected room owners to help mitigate these issues, and when they are present, it is almost unheard of for serious problems to occur. Slytherincess and Praxis have done an outstanding job of keeping chat on track. However, and through no fault of their own, they obviously can't be in chat at all times. When they aren't there, a slight nudge can send the room careening off the rails.
How do we deal with this?
