Hello, I'm J. M.. I noticed that you added or changed content in an article, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page. Thank you. —J. M. (talk) 21:26, 19 November 2020 (UTC)

Please do not add or change content, as you did at Juan Martín del Potro, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you.—J. M. (talk) 14:42, 20 November 2020 (UTC)

Please stop your disruptive editing. If you continue to add unsourced or poorly sourced content, as you did at Juan Martín del Potro, you may be blocked from editing. —J. M. (talk) 15:19, 25 November 2020 (UTC)
