This is a page to track passive-spamming by online gambling sites worldwide, who have usurped over 50,000 domains thus far (December 2025). They go by many names; one is Judi which is Indonesian for gambling; Indonesia was a pioneer of this predatory scheme, now copied around the world.

This page is also to request domains to be usurped. Simply add it to the list below, "Domains to be usurped"

Background

[edit]

When a domain expires or is abandoned by the original owner, anyone can re-register and take possession. They then control all links to those domains from all Wikipedia projects and can redirect to their spam site. This is "passive spamming" since no edits to Wikipedia are required. Gambling sites around the world are systematically monitoring all domains linked from Wikipedia (10s of millions), determining when they expire, and taking possession. For more information about online gambling sites see "Inside the Dark and Predatory World of Crypto Casinos" (New York Times subscription). It is a large complex ongoing problem impacting every Wikipedia project.

The original discussion is Wikipedia:Link rot/URL change requests/Archives/2021/November § Daftar Situs / Judi Slots.

The problem was first identified by User:Lyndaship.

Name

[edit]

The gambling sites use different names. "Judi" means "gambling" in Indonesian. Other commonly associated terms:

What is being done

[edit]

On enwiki, the bot WP:WAYBACKMEDIC can mark citations with usurped domains, for example adding archive URLs and changing to |url-status=usurped. The bot is run by User:GreenC, the author of this page. It follows the process outlined at WP:USURPURL.

For other wikis, there is IABot which runs on 95% of the Wikipedia languages, plus other projects. The domains can be set to "dead" via the IABot interface, and whenever the bot encounters a citation with that domain it will add an archive URL. However this is not a proper anti-usurpation method, it does not change to |url-status=usurped and other things so it is incomplete.

For everything else, nothing is done, it is up to the local wikis.

Edit filters might be used, but since this is passive spamming, and there is no evidence the spammers are actively spamming, the edit filter can cause new problems such as blocking attempts to add archive URLs, blocking attempts to fix the problem - edit filters are not recommended unless there is good reason such as active spamming.
