What Archivebate is and why it spreads fast
Archivebate is a tube site, which means leaked videos are usually shown as individual watch pages and may also appear through search, tags, performer names, thumbnails, and related-video areas.
That matters because removing one visible page may not be the whole job. A single leak can create several URLs that need to be listed in the takedown, and Archivebate has a known mirror count of 1, so you should treat the cleanup as both a site removal and a mirror/search cleanup.
Google has 731,296 Archivebate URLs flagged, which gives you a sense of how much of the site can surface in search. This is why Google delisting should be handled alongside the Archivebate removal, not as an afterthought.
