There are a few other things to keep in mind as well:


 * Don't be rude. No matter how obnoxious vandals are, you shouldn't be rude, especially when leaving warnings. Annoying someone who already disregards policies is unlikely to make them respect other policies. So be polite, but firm, when dealing with vandals. If you find it hard to maintain a level head when dealing with someone, ask for help.
 * Don't disregard policy. Reverting vandalism doesn't grant you any special status nor does it make you superior. Egregious abuse of policy may get you blocked, as well as the vandal. If you're an admin, do not abuse your granted powers. Finally, Ignore all rules shouldn't be invoked if you don't have other arguments to back yourself up with.
 * Do not confuse vandalism with content disputes. Changing an entry's content to statements with which you disagree does not necessarily constitute vandalism. The proper channel to handle such cases is through dispute resolution.
