To provide more details about the Tor Project Forum, the Tor Project team do not really moderate it. The act of manual moderation itself acts as a deterrent to casual opportunists to compose in line with the forum rules, but there are still circumvention methods available to those who know how the system works.
Over here on the Purism community forums, moderator presence has been minimal throughout its history, so when @JCS was interested in appointing a community moderator, I immediately expressed my interest in the position.
I did not receive a response back, so instead, I flag topics or posts in the wrong category in the shadows most of the time, while offering support using various methods. @irvinewade has been invaluable with diligently responding to them.
