I'll go first: r/kitty. One of the hundred grillion cat subs back on Reddit, the culture in this one was you posted a cat picture, and the only word allowed in the title or in any comments or replies was "Kitty."
Someone is using that subreddit for covert communications, I just know it. Either on the level of "if u/PM_me_your_nostrils posts an orange cat, we attack at dawn!" or there's some steganography going on with the pictures, but that subreddit was too stupid to be as active as it was.
The Jan 6th temper tantrum was instigated as a response to the BLM and other Covid-era protests. The owner class was getting nervous about the working class protesting about things that matter, so they riled up some of their disposable morons to storm the Capital as a way to discredit direct action. And we're already seeing the effects; whether it's a labor strike or a student sit-in, we're told by centrists to "protest peacefully" and not inconvenience anyone, aka don't protest.
It took them forever to derail that one and they learned a lot from it. We have been in outright class war ever since and most people don't even know since they are busy fighting culture war
