Hello, I'm Materialscientist. I noticed that you made a change to an article, Jun Matsumoto, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Materialscientist (talk) 10:29, 26 August 2021 (UTC)

Please stop your disruptive editing. If you continue to blank out or remove portions of page content, templates, or other materials from Wikipedia without adequate explanation, as you did at Jun Matsumoto, you may be blocked from editing. -- ferret (talk) 12:33, 26 August 2021 (UTC)
