Using KickassTorrents is potentially illegal, explains Make Tech Easier. Using a torrent client is not inherently illegal, but there are frequent issues with intellectual property rights. Many torrent sites facilitate the transfer of illegally acquired content, and a person downloading protected data breaks the law.
What makes the issue difficult is that copyright laws vary from country to country. To use a site such as KickassTorrents legally, the user must be familiar with the laws of his country and be certain that the content he downloads does not violate copyright. The torrent protocol is not exactly the same as piracy, but downloading protected content is illegal regardless, notes Make Tech Easier.
