You make a very valuable point here and may not have even know how important it really is. When someone pops up again every 2-4 years with heavy use during an election cycle and has had absolutely no board activity at all in between, they are very suspect as provocateurs.
One more thing. I have never understood the secrecy about who the moderators are. I am a moderator on another board and on the about page, it list and identifies the moderators. But here you don’t know who you are dealing with, and let me tell you, we have had some $#@#$%^&%$ moderators in the past.
