Hello, I'm Hayman30. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Pollution prevention— because it did not appear constructive. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.

Please do not add commentary, your own point of view, or your own personal analysis to Wikipedia articles, as you did to M. M. Keeravani. Doing so violates Wikipedia's neutral point of view policy and breaches the formal tone expected in an encyclopedia. Thank you. Dl2000 (talk) 00:34, 12 November 2017 (UTC)

Please refrain from making unconstructive edits to Wikipedia, as you did at Mehreen Pirzada. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. Dolotta (talk) 18:39, 20 June 2018 (UTC)

reliable sources
If you are going to make significant changes to content to an article as here, please make sure you cite a reliable source. I have reverted for now, until you can provide a reliable source. --David Tornheim (talk) 08:08, 25 December 2018 (UTC)
