I don't know who you are Mr. Kickyass, or who you're affiliated with, but Internet censorship is a real thing, and propaganda isn't something that's limited to just the Russians. If you don't think political campaigns have a list of daily talking points and news spins, or that they would engage their campaign staff to disseminate information online, that's on you.
This guy treated it as a part-time job and monitored several social media web sites, posting with multiple identities, to push stories for Hillary and other Democrats during the 2016 election cycle. He's a really sharp guy with a solid career, not some dufus posting random opinions on politics.
Not to say there aren't other people like this out there. Every time a significant politician posts on Twitter, there are a number of people rushing in to reply with their contrarian views or to push their own agenda. Think of this as playing out in an organized fashion.
I'm sure Thriller and others believe in the information they're posting, or in the candidates or policies they're lobbying for, as did the person I'm referring to. They've just chosen to use a sports message board as their venue to push their content out, with the zeal and regularity of a campaign staffer or dedicated lobbyist.
