Recently, I've realized I'm talking with a more bots here on HN. I'll read a weird reply to someones comment shaming them and praising China/Russia/etc..., look at the poster, and realize their account was just created and often gets flagged and taken down. HN is an ideal place to hit the minds of very influential people. Reddit is the place to hit very influenceable people.
(And nah, HN is a terrible place to hit the minds of people that influence whether their country is sympathetic towards rival superpowers, and Reddit is worse...)
