User blog comment:John Breasly/Warning, approaching spammers/@comment-3416406-20111001175434/@comment-1732082-20111001180031

We need to block, revert and ignore. If the user edits one time, undo the edit. If they edit more than 1 time, rollback. Another admin can block while the other is reverting. A rollbacker can tell an admin if they see any spammers so we can block them.
