Months ago there was a post on 8kun that the government in USA is planning to arrest people as domestic terrorists for posting on 8kun. I thought I saved a screengrab but can't find it, the post was like this- "I am a federal agent. Since you people love predictions so much, here is one for you. If you have posted on this website in the last 4 years, you will be arrested during Thanksgiving week."
Probably it was only a glow hoax to try to scare people away from interacting. But on the other hand I think the psychos in power are bold enough to try something like that now. And we have seen that the agencies and judicial system will allow them to do anything.

Hours ago there was also a "final warning" threat on 4chan - pic related.

This is probably all nothing, but just in case, for anyone who posts statements or memes or content on a chan, or Gab, and especially on any other site where users are not anonymous, I encourage those pepole to encrypt their operating system drive. And encrypt any other drives or folders containing content that could be labelled proof of being anti-government, anti-vax, anti-immigration, anti-trans, anti-gay, pro-gun, pro-white, pro-Bible, a believer of end time prophecies, a prepper, or etcetera.
I'm not expert in encryption but what I've heard is to use Veracrypt, not Truecrypt, and to select two different forms of encryption not just one, and to create a password at least 18 or 20 characters long. Can a tech expert provide more advice?
For those that use a phone or tablet, or have content in the cloud or backed up to the cloud, there is nothing I know about that might help.
If someone wants to repost this to 8kun and Gab, I don't post there.
