There is something that can be said for forums that have a means for arbitrating disagreements openly in full view of their members and readers.
It can be said that they have honor and integrity. They seek the truth and act accordingly with justness.
While I have been a member of several forums, about a dozen I would say in the past ten years, I have read what people type at hundreds of forums, think tanks, bulletin boards, blogs and so on. Many of those forums, such as this one for the astronomy picture of the day, must have something to hide as they do not show who is banned or why they were banned. One has to wonder, why that is?
