This is a warning; not a suspension.
He has time to look over what has been posted and think about what is unacceptable. If he continues to say that no evidence has been supplied he will be given 24 hours to think about it.
He may honestly believe that it isn't
good evidence but he needs to take each piece of evidence and point out what is wrong with it not simply say there has been none supplied.
He also needs to explicitly respond to what others are asking. He has been asked to acknowledge that something as been supplied and to comment on it. He has avoided doing that. To continue to avoid it will result in a suspension.
Whether there will be one more warning or not depends on the nature of his next posts.
