I've said this before and I'll say it again. As companies realize how much people like reddit as a trusted source of information, they will learn how to optimize reddit. Then it will slowly degrade just like google has.
They've been learning for a long time. Lest we forget reddit was sold to a mass media company in 2006. They didn't buy it to host a charity forum for the good of the internet community. Smart people work in ads and media and they understand the value of propaganda.
Even before 2016 when the Trump campaign used Reddit heavily to subtly and not-so-subtly promote their agenda, Reddit has been an obvious platform for astroturfing.
