Has anyone ever considered including tag-team edit warring as a 3RR violation? When two people act in tandem (unintentionally or intentionally) to make the same revert four times, they may not technically violate the 3RR rule, but they certainly do so in spirit.  This was the problem on both sides in the edit war on the Canada page, and precisely what I wanted to avoid on the Dominion page. Would it not be easier to warn editors as you did here rather than shut down pages for weeks at a time as was done in the Canada case? I'm sure this would cure the escalation problem without blocking access to pages. Any comments on this?
