This rule does not exist anywhere on Steem as far as I can remember. It is made up. Anyways, I belive that the reason for the downvote is quite clear as described on my very first commnet. Your post is not a REVIEW but has the "realityhubs" tag. This is considered as SPAM which triggered the downvote on your post. I hope this is clearly explained now? There is no hater, unfriendliness or xenophobia here.
