Hello, I'm Serols. I wanted to let you know that one of your recent contributions—specifically this edit to Modulation (music)—has been undone because it appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Please take a look at the welcome page to learn more about Wikipedia. If you have any questions, you can ask for assistance at the Help desk. Thank you. Serols (talk) 17:45, 4 January 2022 (UTC)

You may be blocked from editing without further warning the next time you insert a spam link. Persistent spammers may have their websites blacklisted, preventing anyone from linking to them from all Wikimedia sites as well as potentially being penalized by search engines. jp×g 20:15, 4 January 2022 (UTC)
