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.
content warnng: Magic The Gathering
facts: a couple of weeks ago the commander rules committee, the independent group that governs the popular Commander format, started receiving death threats after they banned some boring ass broken cards (jeweled lotus? dockside extortionist? nobody is ride or die for those)
as a result, the rules committee turned over control of the format to Wizards of the Coast / Hasbro, the makers of magic the gathering
fact: last year after some magic the gathering content was leaked, Hasbro send literal pinkertons to harasss the youtuber leaking it and recover the leaked goods
conspiracy theory: hasbro hired the pinkertons to make those death threats against the rules committee so that hasbro could seize control ove the most popular independent format of magic
