This is the rule I was worried about. This is why I deleted my comment. It is in the Forum Rules topic with the sub heading general conduct.
" As stated further in the forum rules, moderators have no obligation to explain why they have taken the moderating action they have so if you publish a thread wanting to know why your thread was closed or demanding an explanation from the moderators or complaining about moderation, you are creating unnecessary drama and you will be banned from the forum. The moderators are often quite receptive to polite, PRIVATE questions asked to further understanding of the actions taken but they are busy people who may not have to answer every question. "
