Hello, I'm Nihonjoe. I noticed that you recently removed content from Akihabara massacre without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use your sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. ···日本穣 · 投稿 · Talk to Nihonjoe · Join WP Japan! 17:07, 27 October 2021 (UTC)
Hello, and welcome to Wikipedia. You appear to be repeatedly reverting or undoing other editors' contributions at Akihabara massacre. Although this may seem necessary to protect your preferred version of a page, on Wikipedia this is known as "edit warring" and is usually seen as obstructing the normal editing process, as it often creates animosity between editors. Instead of reverting, please discuss the situation with the editor(s) involved and try to reach a consensus on the talk page.
If editors continue to revert to their preferred version they are likely to lose their editing privileges on that page. This isn't done to punish an editor, but to prevent the disruption caused by edit warring. In particular, editors should be aware of the three-revert rule, which says that an editor must not perform more than three reverts on a single page within a 24-hour period. Edit warring on Wikipedia is not acceptable in any amount, and violating the three-revert rule is very likely to result in loss of your editing privileges. Thank you. ···日本穣 · 投稿 · Talk to Nihonjoe · Join WP Japan! 16:38, 28 October 2021 (UTC)
