They sure tried, and there were many , some were even established forum owners whom this forum has by now left in the dustbins of the history rankings. Others were pests who'd re-name themselves and come back again and again. I can't understand why anybody'd behave the way they did. Its only an element - iodine.
My read is that they're possessed by some evil spirit, because Iodine is good. Had we been discussing arsenic or plutonium, they wouldn't have been upset, but since it was iodine, and Iodine is good for people, the evil spirits couldn't stand to see people getting well again.
