Please refrain from repeatedly undoing other people's edits. It appears you may be engaged in an edit war. The three-revert rule (3RR) prohibits making more than three reversions in a content dispute within a 24-hour period. Additionally, users who perform a large number of reversions in content disputes may be blocked for edit warring, even if they do not technically violate the three-revert rule. Rather than reverting, please discuss disputed changes on the talk page. Thank you.
