One point to remember about 3RR: if you get as far as *three* reverts in 24 hours, something's badly wrong. Allowing three reverts in 24 hours is one of the things Wikipedia allows but does not condone.
Hear, hear!
I revert once, with a terse edit comment.
XYZ reverts.
I revert again, with a careful edit comment saying "see Talk" and a good reason in the talk page.
If, at this point, XYZ reverts again, I don't know what the most effective thing to do is. But I do know one thing for sure: reverting a third time is not it.
Now if--and the thing is possible--goaded beyond endurance, I were to continue with further reverts at various points in time... well, jeez, I'm skating on thin ice. I know it, everyone knows it. And suppose an admin _did_ block me, why would I even bother to complain? Why not just accept the slap on the wrist and wait out the 24 hours?
