This particular user seems to be on a tag wiki editing spree. I've noticed quite a few tag edits which are very trivial and offer very less information. And I happened to see quite a lot of the tag wiki edits in the reviews queue even today.
My question is, how do I flag such an user for moderator attention? Because there is no flag option in the review page of a tag wiki edit, nor does the tag page have an option to flag.
