I suppose a case could be made for him to be tolerated on the adrenal forum, but I cringe watching him harass people on the nutritional balancing forum. The Forum Guidelines there are clear, it's a support group for their program which includes supplements and he is there again trying to convince people to not take supplements.
I used to think he was misguided but now I think he has an actual troll intent.
Send him off to the banana people and let them be happy.
