Hello, I'm Serols. I wanted to let you know that one of your recent contributions—specifically this edit to History of water filters—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) 15:34, 9 March 2021 (UTC)

Please do not add inappropriate external links to Wikipedia, as you did with this edit to Wastewater. Wikipedia is not a collection of links nor should it be used for advertising or promotion. Inappropriate links may include, but are not limited to, links to personal websites, links to websites with which you are affiliated and links that attract visitors to a website or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the article, please discuss it on the article's talk page rather than re-adding it. Thank you. Serols (talk) 15:49, 9 March 2021 (UTC)

Please stop your disruptive editing. If you continue to add inappropriate external links to Wikipedia, as you did at Industrial wastewater treatment, you may be blocked from editing. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings.
