User talk:Ctafur

Welcome!
Hello, Ctafur, and welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay. Unfortunately, one or more of your recent edits did not conform to Wikipedia's verifiability policy, and may have been removed. Wikipedia articles should refer only to facts and interpretations verified in reliable, reputable print or online sources or in other reliable media. Always provide a reliable source for quotations and for any material that is likely to be challenged, or it may be removed. Wikipedia also has a related policy against including original research in articles.

If you are stuck and looking for help, please see the guide for citing sources or come to the new contributors' help page, where experienced Wikipedians can answer any queries you have! Here are a few other good links for newcomers:

I hope you enjoy editing here and being a Wikipedian! Please sign your name on talk pages using four tildes ( ~ ); this will automatically produce your name and the date. If you need help, check out Questions, ask me on my talk page, or. Again, welcome.

Hello, I'm DVdm. I noticed that you made a change to an article, Probability, 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. DVdm (talk) 15:41, 28 February 2020 (UTC)

Please do not add or significantly change content without citing verifiable and reliable sources. Before making any potentially controversial edits, it is recommended that you discuss them first on the article's talk page. Please review the guidelines at Citing sources and take this opportunity to add references to the article. DVdm (talk) 21:03, 28 February 2020 (UTC)

Note: see wp:verifiability and wp:BURDEN; Find a proper source for your addition, bring it to the article talk page, and discuss. That is how Wikipedia works. See also wp:edit warring and wp:BRD. - DVdm (talk) 21:06, 28 February 2020 (UTC)

Please do not add unsourced or original content. Doing so violates Wikipedia's verifiability policy. If you continue to do so, you will be blocked from editing Wikipedia. DVdm (talk) 23:09, 28 February 2020 (UTC)

Note: Youtube is not a reliable source. I told to take your source to the article talk page and discuss. Please do, unless you want to end up blocked. - DVdm (talk) 23:11, 28 February 2020 (UTC)

You may be blocked from editing without further warning the next time you add unsourced material to Wikipedia, as you did at Probability. - DVdm (talk) 10:40, 29 February 2020 (UTC)

Note: the comment that you make is not present in the source that you provided. This is your final warning. - DVdm (talk) 10:40, 29 February 2020 (UTC)
