I don’t disagree with your intentions at all, and as a deeply cynical person myself, I appreciate your visceral skepticism. I am just having trouble envisioning a specific example where any concerns about a vendor being a moderator would ever actually apply to something that wouldn’t immediately be caught and remedied. I mean: how do you operationally define the trouble you suppose a moderator who is also a vendor could cause? Are you supposing a vendor who has moderator powers would delete critical things said about them or their products on KT? That’s about the only thing I could imagine where there would be any kind of conflict of interest, but one thing that @Manofinterests didn’t mention in the rules (and which, Huey, I think we should add explicitly), is that moderators have to recuse themselves from any moderator activity when the matter under discussion concerns them or any of their projects (whether for-profit or not). That rule applies to board member voting as well, incidentally. Failure to do so is sufficient cause to be drummed out of the position.
That sort of misuse of power would obviously instantly get reported to the board members and other moderators and/or posted to Reddit, etc., so it wouldn’t be possible to get away with it for even a few hours. And, anyway, there is no reason that being a vendor would make one more susceptible to this temptation than any other non-vendor member of the community feeling tempted to delete or censor criticism about his personal statements or projects. One doesn’t have to sell things sometimes to be vulnerable to conflicts of interest. Both vendors and non-vendors alike should be held to the standard of self-recusal on matters that relate to them personally; in my opinion, that is the thing that really matters.
As I say, I think being a “vendor” as we’re broadly defining it here is a sign of personal investment, maturity, seriousness, commitment to the hobby and community, etc., and if anything it should be an asset rather than something to be considered a compromising attribute. I believe in the power of incentives to help ensure ethical behavior, and a vendor has far more to lose by misbehavior as a moderator or board member than someone more casually connected to the hobby. I think we need more of them, particularly on the board, rather than fewer—especially to act as checks on each other and to avoid any potential appearance of small club of folks trying to “control” things. (Though, as I’ve said, “control” in the case of KeebTalk just means being responsible for making sure the server bills get paid and making sure posts that are 100% profanity or spam get deleted. Wielding the Ring of Power this is not. )
FWIW, it should also be noted that both the board and mods team are in favor of an exceedingly light hand at moderation. You can see from the various posts and discussions from the site announcement that we’ve let all manner of critical, cranky, and downright hostile posts remain in place, unfiltered and unedited, as long as they had any semantic weight whatsoever (we deleted one post that was nothing but 100% profanity, and even that would have been fine if it were, like, 99% profanity and 1% criticism). There would be nothing more self-defeating than trying to censor or edit criticism of one’s own work.
