Just to clarify, the article was under two weeks of partial protection (which is generally considered reasonable) and then upgraded to full protection because of the edit war over this; the expiry date on the upswitch was left as the original expiry date on the two-week-partial. I'd note, however, that it's not just one or two accounts making problematic edits — if you review the edit history, you can see that there's been a near-constant barrage of problematic and inappropriate edits from a remarkable variety of sources.
