Disable individual boards
I wonder why they (the mods) couldn't just disable the boards that were out of control? If they can suspend individual accounts, why not individual boards that were consistently violating the rules?
Removing/blocking the message board feature from troublesome boards I think would have been a better solution instead of punishing all the boards. I'm not saying our board was free from drama. I just don't think it will benefit this site to remove a feature that many come to for peer reviews, questions, and community based on a shared interest.
You don't have to attend every argument you are invited to.
