Not sure why you are downvoted. But some subs like politics and worldnews are just pure propaganda and bots driven at this point.
I'm curious, what's your criteria for propaganda? Is it just content/viewpoints that you don't like? Likewise, for bots. Can link to some examples of bot-like behavior that's happening on reddit? Preferably provide hard evidence of some kind, like the ones done for this story: https://www.nytimes.com/interactive/2018/01/27/technology/so...
Either subscribe to a bunch of them, one for each world view, or just classify reddit as a flawed news source and move on to something better.
