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.
Anti-perspirant causes breast cancer. You look at data for Japan back in the 90’s-2000s and breast cancer was like 80 times less prevalent in Japan vs the US. Now Japanese are starting to use it more and breast cancer instances are raising to be more on-par with the US. The NIH did a study that was inconclusive so everyone assumes its not true. However, if you read the study you realize exactly how inconclusive it is, and that the answer was truly more along the lines of: “We don’t know”.
