Who was behind the arrest of the well known torrent site kickass ?

Artem Vaulin, the alleged owner of the torrent directory service KickassTorrents, was arrested in Poland earlier this week, charged with copyright infringement and money laundering. As we dig deeper as to what exactly happened, it turns out Apple and Facebook were among the companies that handed over data to the U.S. in its investigation. Department of Homeland Security investigators traced IP addresses associated with KickassTorrents domains to a Canadian ISP, which turned over server data, including emails. At some point, investigators noticed that Vaulin had an Apple email account that was used to make iTunes purchases from two IP addresses -- both of which also accessed a Facebook account promoting KickassTorrents.if you're wondering where exactly iTunes came into play, here's a further explanation. It all started in November 2015, when an undercover IRS Special Agent reached out to a KickassTorrents representative about hosting an advertisement on the site. An agreement was made and the ad, which purportedly advertised a program to study in the United States, was to be placed on individual torrent listings for $300 per day. When it finally went live on March 14th 2016, a link appeared underneath the torrent download buttons for five days. Sure it was a short campaign, but it was enough to link KAT to a Latvian bank account, one that received $31 million in deposits -- mainly from advertising payments -- between August 2015 and March 2016. Upon further investigation of the email accounts, and corresponding reverse lookups, it was found that the account holder had made a purchase on iTunes.
