There is another way to detect 100% reverts. It won't catch manual reverts that are not 100 accurate but most vandal patrollers will use undo, and the like.
For every revision calculate md5 checksum of content. Then you can easily look back say 100 revisions to see whether this checksum occurred earlier. It is efficient and unambiguous.
This will work for any Wikipedia for which a full archive dump is available.
