A tag has been placed on Draft:David Simchi-Levi requesting that it be speedily deleted from Wikipedia. This has been done under section G12 of the criteria for speedy deletion, because the page appears to be an unambiguous copyright infringement. This page appears to be a direct copy from https://executive.mit.edu/faculty/profile/51-david-simchi-levi. For legal reasons, we cannot accept copyrighted text or images taken from other web sites or printed material, and as a consequence, your addition will most likely be deleted. You may use external websites or other printed material as a source of information, but not as a source of sentences. This part is crucial: say it in your own words. Wikipedia takes copyright violations very seriously and persistent violators will be blocked from editing.

If the external website or image belongs to you, and you want to allow Wikipedia to use the text or image — which means allowing other people to use it for any reason — then you must verify that externally by one of the processes explained at Wikipedia:Donating copyrighted materials. The same holds if you are not the owner but have their permission. If you are not the owner and do not have permission, see Wikipedia:Requesting copyright permission for how you may obtain it. You might want to look at Wikipedia's copyright policy for more details, or ask a question here.

If you think this page should not be deleted for this reason, you may contest the nomination by visiting the page and clicking the button labelled "Contest this speedy deletion". This will give you the opportunity to explain why you believe the page should not be deleted. However, be aware that once a page is tagged for speedy deletion, it may be deleted without delay. Please do not remove the speedy deletion tag from the page yourself, but do not hesitate to add information in line with Wikipedia's policies and guidelines.

Your recent article submission to Articles for Creation has been reviewed! Unfortunately, it has not been accepted at this time. The reason left by Justlettersandnumbers was:

This submission is not adequately supported by reliable sources. Reliable sources are required so that information can be verified. If you need help with referencing, please see Referencing for beginners and Citing sources.

 The comment the reviewer left was:

Practically every source in the page appears to be written by, or closely connected to, him; Wikipedia is only interested in what is reported in independent reliable sources. Page creator appears to have an undisclosed conflict of interest.

Please check the submission for any additional comments left by the reviewer. You are encouraged to edit the submission to address the issues raised and resubmit when they have been resolved.

• If you would like to continue working on the submission, go to Draft:David Simchi-Levi and click on the "Edit" tab at the top of the window.
• If you now believe the draft cannot meet Wikipedia's standards or do not wish to progress it further, you may request deletion.

Hello, Shiyuanw. We welcome your contributions, but if you have an external relationship with the people, places or things you have written about in the page Draft:David Simchi-Levi, you may have a conflict of interest (COI). Editors with a COI may be unduly influenced by their connection to the topic. See the COI guideline and FAQ for organizations for more information. We ask that you:

• avoid editing or creating articles about yourself, your family, friends, company, organization or competitors;
• propose changes on the talk pages of affected articles (you can use the ((request edit)) template);
• disclose your COI when discussing affected articles (see WP:DISCLOSE);
• avoid linking to your organization's website in other articles (see WP:SPAM);
• do your best to comply with Wikipedia's content policies.

In addition, you must disclose your employer, client, and affiliation with respect to any contribution which forms all or part of work for which you receive, or expect to receive, compensation (see WP:PAID).

Editing for the purpose of advertising, publicising, or promoting anyone or anything is not permitted. Thank you. Justlettersandnumbers (talk) 20:50, 12 June 2019 (UTC)[reply]

Just to declare, I have a really weak conflict of interest with the subject in a wikipedia page I edited. Not families, friends, employer or employee, and there is no financial or professional connection. I just know him. He is famous in the area of operation research and operation management, and I'm a student majoring in this area.
