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.
I have never seen so much money spent on something so boring and predictable. Don’t get me started on Avatar 2, that was a 3 hour water simulation that still somehow managed to be naff because of annoying cartoony characters.
My pet (very) silly theory is that both were a cover for military investment in fluid dynamics simulations and they had to hide hours of 3d renders and water simulations in plain sight.
