I don't think I'll be able to respond effectively until someone tells me how one "explains things" to Terrell Owens, Dennis Rodman and John Rocker, but trying anyway...
The power that moderators have is balanced by a responsibility to the goals of EvC Forum: productive, constructive, evidence-based discussion. Using their personal judgment, moderators intervene when they see behavior that acts as an obstacle to these goals. [forum=-28] is intended not so much as a place where one can continue debating with those restricted from the main forums, but more where you can help the residents develop the skills necessary to gaining a return of full privileges.
In this light, complaining that JAD is "doing it again" is redundant. Of course he's doing it again. That's why he's restricted to [forum=-28]. The task (a hopeless one in his case, I'm afraid, but it can be fun to try) is to help JAD see the light so he can return to being (or begin being, actually) a constructive member of EvC Forum.
If, like me, you don't believe JAD is helpable, then stay out of his [forum=-28] threads. If you believe his personal comments about you merit a response (you should be asking yourself why the ravings of a lunatic merit a response), then open a thread in [forum=-14].
Keep in mind you're not alone in being abused by JAD. We moderators are apparently the reincarnation of Atilla the Hun, but we don't respond to these charges because we're pretty sure that anyone seeing them will consider the source, and ravings are fairly easily recognizable by most people anyway. In other words, excoriations from JAD shouldn't merit much if any attention.
I will add that the recent posts from Mammuthus and Pink Susquatch seem more oriented toward continuing the discussion than toward helping JAD "recover", but as long as they stay focused on the issues that is certainly acceptable. We haven't actually figured out how to make [forum=-28] work yet. Responding to a Boot Camp inmate not with a response to their argument but instead with advice about how to improve their style is terrifically condescending, and more likely to cause upset than improvement, yet that's what we've asked. On the other hand, Boot Camp at least removes those incapable of constructive discussion from the main forums.
Summing up, even though I think most people confined to Boot Camp will be irremedial, I still think it, or something like it as we learn to use it better, will raise the quality in the main forums.
