Removing your comments which have been replied to is a serious violation of WP:TALK; more so when it's not obvious that it's your comments, but possibly an IP's or another editor's. If you do this again, you should be blocked. — Arthur Rubin (talk) 10:17, 12 July 2013 (UTC)

Your recent editing history at Talk:Pythagorean triple shows that you are currently engaged in an edit war. Being involved in an edit war can result in your being blocked from editing—especially if you violate the three-revert rule, which states that an editor must not perform more than three reverts on a single page within a 24-hour period. Undoing another editor's work—whether in whole or in part, whether involving the same or different material each time—counts as a revert. Also keep in mind that while violating the three-revert rule often leads to a block, you can still be blocked for edit warring—even if you don't violate the three-revert rule—should your behavior indicate that you intend to continue reverting repeatedly.

To avoid being blocked, instead of reverting please consider using the article's talk page to work toward making a version that represents consensus among editors. See BRD for how this is done. You can post a request for help at a relevant noticeboard or seek dispute resolution. In some cases, you may wish to request temporary page protection. — Arthur Rubin (talk) 10:19, 12 July 2013 (UTC)

Please do not delete or edit legitimate talk page comments, as you did at Talk:Pythagorean triple. Such edits are disruptive and appear to be vandalism. If you would like to experiment, please use the sandbox. Thank you. —David Eppstein (talk) 19:02, 14 July 2013 (UTC)
