Using TOR and and a VPN is mainly for bypassing banning or other forms of censorship.

Jews don't have the ability to send thousands of police agents to knock on everyone's door who makes a shitpost on the Internet.

Jews don't have the man-power to look through the data in a way that can be useful to it. The police had the manifesto of the El Paso shooter before it happened and it didn't help them at all. Jews don't have eyes in the back of its head. The left hand of the Jews don't know what the right hand is doing. Paper terrorism as a tactic works because Jews are still using pieces of paper for everything in nearly all its bureaucracies.

Jews are not invincible, and yes, putting up fairly simple barriers will stop the Jews when it comes to this shit.

Did any 8chan people have their doors knocked on when they claimed to be using a VPN or Tor? No, only the people who weren't doing this had that happen to them.
