Requests for comment/Global ban for Musée Annam

From Meta, a Wikimedia project coordination wiki

The following request for comments is closed. The request for comment has been resolved by enacting a global ban.

Opening statement

Hi, I'm NguoiDungKhongDinhDanh, a somewhat trusted user on viwiki and patroller elsewhere. I, among others, have been cleaning up this user's mess for a while and personally think he deserves a global ban for harassing, spamming fake files and tendentious editing. I'm not a good writer, so pardon my English.

Uploading fake files and spamming

This section needs expansion.

Tendentious editing

Being a Chauvinist, he edits largely for promoting Vietnam history and Vietnam in general, violating projects' NPOV policies. For example, among a handful of normal edits, this edit on Wikidata contains nothing but a sentence that says "Xóa đường lưỡi bò, bảo vệ Tổ Quốc" ("黄沙、長沙、的越南!反對中國侵略東海!" in the next one). On occasions, he even violate copyright law by pasting a lengthy text, as seen here. He is also known for abusing a very old way of writing that can be seen pretty clear via this instance: "Kênh truyền-thông đại-chúng Việt-Nam" For your information, this alias were written with three Sino-Vietnamese words in which syllables are connected by hyphens. This is a very old way of writing that cannot be found in any modern Vietnamese books and are generally no longer used, even by the elders; he chose this strange way just for promoting the so-called "magnanimous history of Vietnam". In some other edits, he added content that were originally made up by his own, as seen here. These include fake files he uploaded to Commons using multiple accounts listed below and their global usage.


Lệ Xuân, Donald Trung and Băng Tỏa are, among others, three of his favourite harassing targets. In my opinion, they were targetted for two reasons:

  • They nominated his files for deletion, reverted or fixed some of his tendentious edits, or reported him to sysops (main reason);
  • They are of Vietnamese descendants, but live in another country (overseas Vietnamese);

Most of his edits were suppressed or (revision) deleted, but those with advance permissions can still see some of them at (most, if not all, are in Vietnamese, I suppose):

...and some other tens of small wikis.


He has been attempting to out Lệ Xuân for a while now. For example here (only stewards or vi admins can see it).

(Dynamic) List of sockpuppets


These accounts were taken from c:Category:Sockpuppets of Đăng Đàn Cung and linked ones. For stewards: When closing this RfC as successful, please go to Vandal.

Extended content


In short, he was blocked at least 90 times on 12 wikis (commons, data, dawiki, dewiki, enwiki, idwiki, nlwiki, plwiki, svwiki, viwiki, viwikt, zhwiki) and locked globally 29 times in over 15 years, mostly for sockpuppetry, harassing/incivility, vandalism, spreading hoaxes and sometimes faking VTRS permissions, yet we see no sign of good editing (see #Behaviour above).


He is also suspected to use these IPs:

Criteria confirmation

  • The user demonstrates an ongoing pattern of cross-wiki abuse that is not merely vandalism or spam.
    Not vandalism:  Yes
    Nor spam:  Yes
  • The user has been carefully informed about appropriate participation in the projects and has had fair opportunity to rectify any problems.
    Warnings from admins:  Countless
    Time given to change: He got his first blocked on Mar 18 2007 for vandalising articles after warning(s). Two of his edits back then were replacing all content with defamation: "'''ĐỒ NGỐC ! KHÔNG Ở VIỆT NAM THÌ BIẾT GÌ ?'''" (463545) and "<math>'''BỌN NGỐC !'''</math>" (467055). Recently, on Dec 25 2021 (after nearly 15 years), he insults Lệ Xuân on cawiki (see here if deleted). It is clearly that he have not changed any better, only worse.
