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 think there are secret grades of retail products and stores get these differently graded products based on the "tier" of store they are. So Dollar General candy maybe didn't pass QA to be sold at, say, Harris Teeter. I'm not talking about selling a package with less candy in it. I mean, for example, that the candy at the Dollar General may inexplicably have a higher percentage of adulterants or slightly off on flavor so it gets assigned C grade so it goes into packages of candy sold at C grade markets.
It's probably not a conspiracy so much as I don't know what industry jargon to search for to find out more information.
I know that some of them have their own in-house brands, which can actually be pretty good especially given the price. But like, they've also got national brands in there, like say M&Ms, you think the Mars company sells the M&Ms with off-center Ms to the dollar stores and the centered Ms to Whole Foods?
