Well, I have some thoughts, probably not particularly helpful.
FWIW I've been involved in moderating various forums, all technical, since 1986 (BIX on a 2400 baud modem).
This board is the admins' sandbox, not the members'. The admins can legally take any actions they see fit to maintain the board as they see fit, including actions that are not covered by the terms of service. However, if they are the mostly rational and fair people I think they are, with the intentions I think they have, they are not going to take actons that destroy this board as a good place to discuss EvC and as a source of quality information.
Banning someone like whatever permanently, or putting he/she "on moderation" as they do over at TWeb, for repeatedly posting drivel is IMHO a slippery slope. Content moderation is dangerous; it can easily become or be seen as favoritism toward a particular point of view.
That said, it appears to me that whatever's actions harmed the board and its reputation, and Lord knows he/she is irritating! I think the admins had to take some action.
But I'm in favor of such action only when things are reaching a boiling point (I would not have been surprised to have been suspended for a day or so after some of my recent posts), or where clear indications of a
factual problem exist that can be effectively argued as a violation of the posted rules. I'm not even sure I would amend the rules to prohibit such egregious lies and whatever's lie about the Bible on Brown's site.
Bottom line: I think whatever should be reinstated, and the board members should each reach an appropriate accomodation with his/her presence with minimal admin intervention. It's the price we pay for an open and frank discussion. Hell, this too shall pass.
