Here is a bot which summarises long text. http://autotldr.io/
I think you will find most of the content on reddit is intelligence services phishing for info, invoking a bit of cognitive dissonance and complementing people's education to bring them up to date for what is acceptable and not in a global world.
Also surprised to see no mention of the fact that reddit is also structured so "humans" can train an AI, just like Google's I'm not a robot is an AI visual recognition training program, which everyone should be familiar with, more so if you are aware of Donald Rumsfeld's Known Knowns speech because you can apply this 4 compartment test to many things in life, including police detective work.
