Help:Rollback

Administrators and editors granted rollback rights can rollback all changes by a user and it is automatically marked as a minor change and gives the following edit summary:


 * ''Reverted changes by User A (talk) to last version by User B

To use bot rollback, you type in the url http://simple.wikipedia.org/w/index.php?title=Special:Contributions&target=Example&bot=1 replacing Example with the user name, then you can rollback edits and hide them from the recent changes along with the rolled back edit, but this should only be used for large amounts of vandalism, like a with vandalbot.
