The article had only just been unprotected after an edit war.  WP:3RR is not a hard-and-fast rule, nor an entitlement: it's a hard limit.  3RR is not the only way to be blocked for aggressive editing, and is not the reason you're blocked here — you revert warred on an article, even though you knew that aggressive editing would be frowned on.  If you'd like the views of another administrator, feel free to bung in a  tag at the bottom of this page, and someone else will come along and review the case.   (befuddle me!)
