User talk:47.18.158.186

August 2019
Hello, I'm MelbourneStar. I noticed that you made a change to an article, Stockfish (chess), 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. —MelbourneStar ☆ talk 17:53, 17 August 2019 (UTC)

 * It is not the responsibility of readers to google information in a Wikipedia article to find out if it is true. A user is not a reliable source because no one knows who the user who added the information is and whether that person is telling the truth.


 * Following are excerpts from relevant Wikipedia guideline and policy pages:


 * No original research. "Main page: Verifiability. Wikipedia's content is determined by previously published information rather than by the personal beliefs or experiences of its editors. Even if you're sure something is true, it must be verifiable before you can add it. The policy says that all material challenged or likely to be challenged, and all quotations, needs a reliable source; what counts as a reliable source is described at Verifiability."


 * Verifiability. "Base articles on reliable, third-party, published sources with a reputation for fact-checking and accuracy. Source material must have been published, the definition of which for our purposes is "made available to the public in some form". Unpublished materials are not considered reliable."


 * Verifiability. "All content must be verifiable. The burden to demonstrate verifiability lies with the editor who adds or restores material, and is satisfied by providing an inline citation to a reliable source that directly supports the contribution."


 * As further information, please note that Wikipedia is not a forum, blog, soapbox, fan site, message board, advice site, advertising vehicle or tabloid. It is an encyclopedia based on reliable, verifiable, third-party sources. It does not publish rumors, gossip, personal opinions, personal experiences, messages, commentary, advocacy, complaints, advice, joke edits, promotional material, original research or unsourced information likely to be changed, challenged or disputed. See also Biographies of living persons, Five Pillars, Identifying reliable sources, What Wikipedia is not, Verifiability, Citing sources, Help:Footnotes, No original research, Manual of Style/Words to watch and Neutral point of view.

You may be blocked from editing without further warning the next time you make personal attacks on other people, as you did at User talk:Donner60. Comment on content, not on fellow editors. Donner60 (talk) 03:34, 19 August 2019 (UTC)
