Hello, I'm Reify-tech. I noticed that you recently removed content from Technetium (99mTc) sestamibi without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. 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.

If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. Beevil (talk) 15:52, 23 June 2019 (UTC)

Hello, I'm ToBeFree. I wanted to let you know that one of your recent contributions —specifically this edit to Breast cancer— 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. ~ ToBeFree (talk) 16:39, 30 September 2019 (UTC)

Hello, I'm Mr.Sarcastic. I noticed that you made a change to an article, Elisabeth Bik, 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. Mr.Sarcastic (talk) 14:54, 7 May 2020 (UTC)

Your recent editing history at Elisabeth Bik shows that you are currently engaged in an edit war; that means that you are repeatedly changing content back to how you think it should be, when you have seen that other editors disagree. To resolve the content dispute, please do not revert or change the edits of others when you are reverted. Instead of reverting, please use the talk page to work toward making a version that represents consensus among editors. The best practice at this stage is to discuss, not edit-war. See the bold, revert, discuss cycle for how this is done. If discussions reach an impasse, you can then post a request for help at a relevant noticeboard or seek dispute resolution. In some cases, you may wish to request temporary page protection.

Being involved in an edit war can result in you being blocked from editing&mdash;especially if you violate the three-revert rule, which states that an editor must not perform more than three reverts on a single page within a 24-hour period. Undoing another editor's work—whether in whole or in part, whether involving the same or different material each time—counts as a revert. Also keep in mind that while violating the three-revert rule often leads to a block, you can still be blocked for edit warring&mdash;even if you don't violate the three-revert rule&mdash;should your behavior indicate that you intend to continue reverting repeatedly.

Please do not add or change content, as you did at Retraction Watch, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. Jonathan A Jones (talk) 18:47, 7 May 2020 (UTC)

Please stop your disruptive editing. If you continue to add unsourced or poorly sourced content, as you did at Retraction Watch, you may be blocked from editing. Jonathan A Jones (talk) 21:01, 7 May 2020 (UTC)
