I don't know if you know this, but every article has a history of changes. Admins look at the diffs of these changes and can see exactly what was added or removed. And about edit-warring and BLP violations, again, the best way to resolve those are using the talk page. For the former the alternative is a game of attritions, and for the latter the possible harm is too great to not arrive at a consensus for the change first. You sure do seem to have something personal against Wikipedia admins, but they don't even get involved unless you've been vandalizing or editing very disruptively. Even then, they are not arbitrators of content, but behavior.
