KickassTorrents is a BitTorrent indexing site which launched in 2008. The site is one of the most popular BitTorrent sites, benefitting from an increasing number of visitors when ThePirateBay was offline for 2 months. The site currently has a global Alexa ranking of 75, and is ranked 29 in India and 98 in the US. SimilarWeb data shows nearly 400 million sites visits a month with 27% of that traffic coming from the US.
In July 2015, it was reported that Google Chrome had started blocking access to the site due to the site containing “harmful programs.”
During the course of 2014 and 2015, the site has moved domain names a number of times. In November 2014, the site moved to Kickass.so. However, the domain was seized by the Somalian registry and the site subsequently hopped to Kickass.im for a 24 hour period. Following action taken by the Isle of Man domain registry to withdraw the domain name, the site moved to its current domain of Kat.cr.
The site derives revenue from advertising and affiliate agreements, some with companies that produce software designed to hide users of BitTorrent from detection by ISPs and monitoring companies.
As with the other sites, no details are provided on the site as to the identity of those controlling the service or where it is physically located, so rights holders have had to seek alternative remedies. In 2012, right holders in Italy, through cooperation with the fiscal police (GDF), were successful in getting the site blocked by all local ISPs. In March 2013, major ISPs in the UK were ordered to block the site. In August 2013, Belgian ISPs started blocking the site and in January 2014, Irish ISPs similarly commenced blocking access to the site. Most recently, in March 2015 Danish ISPs were required to start blocking access to the site.
Kat.cr is currently operating on multiple different IP addresses indicating that is using a form of content delivery network.
