195 was a general dump anything and everything subreddit. Went on a for a long while like 5+ years, started buy a guy and his roommate matt. Suddenly like 2018 a message appeared sticked to the top that said “social experiment completed” and the sub was locked. People moved to both 196 and 197. At the end of 195 it shifted more twords right wing bigotry type memes and screenshots. 196 added a rule to the only rule, bigotry screenshots were restricted to Saturdays which filtered out a lot of hateful content and the void of which was filled with positive more uplifting screenshots and memes. Without the fear of opening up a post and having it be the most bigoted take on something and calling it a meme the posters were able to put out their pride without the fear of hate in return.
The users who wanted to post the bigoted memes went to 197 since they were restricted to Saturdays only. Helped create a divide in 195s two posting groups and overall make 196 the place to be.
Sorry for wall of text but finally some niche lore I could contribute to.
