The authorities in Japan are questioning their power to take on cybercrime that they’re calling for ISPs to block the use of Tor.
The National Police Agency (NPA) is urging ISPs to block customers if they’re discovered to have “abused” Tor. Since Tor routes traffic through many other networks, this could also be an attack on other forms of staying anonymous.
Tor has been used by activists who dwell below repressive governments, and anyone who prefers to do tasks online anonymously, like whistleblowers, for example. The “abuse” of Tor is unclear, and by definition you can’t actually know what an individual does when they are using it seems ban all together is what is intended.
