Wikipedia:Link rot/Usurpations

Usurped domains are used by spammers, squatters, malware, SEO, phishing or other fraudulent activity. Typically they are legitimate domains that expired and were hijacked.

How to usurpify a citation
The following is a decision tree for each citation. It can be followed manually, or implemented algorithmically by bot.


 * Does the source URL have an archive available? If yes..
 * Is it in a CS1|2 template (eg. )? If yes..
 * Add usurped, archive-url and archive-date
 * Is it a square-bracketed or bare URL? If yes..
 * Wrap the archive URL (with or without square brackets) in


 * Is no archive available? If yes..
 * Can the citation be verified if the URL was removed (eg. newspaper or journal content off-line)?
 * Remove the URL and keep the citation
 * Is the citation unverifiable without a URL (eg. web-only content)?
 * Remove the entire citation per WP:V: unverifiable
