Hello, I'm Pkbwcgs. I noticed that you made a change to an article, David Bainbridge, 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. Pkbwcgs (talk) 20:13, 31 May 2018 (UTC)

Please stop your disruptive editing. If you continue to vandalize pages by deliberately introducing incorrect information, as you did at Colleges of the University of Cambridge, you may be blocked from editing. David Biddulph (talk) 19:01, 10 January 2022 (UTC)
