It seems that dimension10 has accidentally deleted this review (I am giving the benefit of the doubt). VK has placed the text of the review here: http://vladimirkalitvianski.wordpress.com/2014/09/06/renormalization-and-gauge-invariance-by-g-t-hooft/
This review was downvoted, it is not a correct review. But it is an informative review, in that people with similar ideas can get a rebuttal of such ideas in the linked discussion to such a review. This is how you best deal with wrong reviews, not by deleting them, rather by responding to them until all the confusions are cleared up. It doesn't take all that long, and it is more helpful to others.
I would like to understand why this was deleted. It is not a good text, but it is an on-topic text, which is roughly at the appropriate level. It might be lacking in meaty stuff, calculations, models, and so on, but the paper it is reviewing is sort of a fluffy thing anyway.
I don't see the point of having a review sections if we aren't going to allow open access, and that includes people who have wrong ideas. Half the criticisms in the world are totally off-base, and you need to get them out in the open, so you can attack the problem at the root. If we wanted to restrict who can say what to a class of people, then you might as well go to a journal. Rebutting VK's nonsense doesn't take long anyway, and it is more helpful for the site than deleting it.
But in any case, deleting or hiding a review is without a doubt a punitive restriction, and it cannot be done at the whim of a moderator, it must be discussed within the community. There is nothing in the text that merited deletion as far as I can see, simply downvotes.
If there is some consensus that this text is inappropriate, I would like to know why. Wrongness is not a reason, there are lots of wrong things in the world that are best dealt with a quick rebuttal and a downvote.
