This is a bit different than the 3-revert/article/day rule. This is a 6-revert/day set-up.

The vote is not going well, but some people have proposed a neat alternative enforcement of the new 3-revert policy: If you revert the same article more than three times in one day, the page gets protected as the version you were reverting. Thus your version gets pushed into the article's history.
Not sure what would happen if more than one person breaks the 3-revert rule on the same page or what would happen for repeat offenders on the same article. But the above mentioned alternative has the advantage that it is a refinement of current practice instead of something really new. More refinements can and should improve the system in the future.
