Are they instructed on talking points or are they surfaced because they adhere to the desired narrative?
a bit of both, If you remember a decade ago when Chapo Trap House got huge, supposedly they're all part of "weird twitter' which basically meant a bunch of guys in a group chat/discord who would retweet/like each others tweets so they'd get insanely high numbers and get more attention on them and they used that same strat to launch their podcast and get a fuck load of subs, then the guys who helped them out also got podcasts. its why Red Scare, Cumtown, TrueAnon, and a bunch of other podcasts from other very online losers got huge and made the hosts about a half million dollars a year. Seriously, for awhile there the top 5 podcasts on Patreon were all started by people that basically lived together. its crazy.
How this relates to BAP and his friends is that its operating under the same idea of that and the reddit powermods who took control of that site. You have these groupchats and because they constantly retweet each other and message each other and workshop tweets, when one has a great talking point, they can get their buddies to repeat it to get the rest of the sphere on board.
depending on where you are at in the totem pole you might just be a small account getting constant retweets and is grateful or you're one of the people in these chat groups.
As much as people shit on reddit, that whole groupthink is a great microcosm of reality, as unidan showed it only takes a small push for people to chose "the correct" take in any thread.
This is what all those dumb posts about the web of the alt-right are about, they trace the activity to certain power accounts who end up getting retweeted or repost each others content and boom, it gets huge. A lot of the time it doesn't though, but because X is all about rewarding content and content creators, if you participate enough you get more clout.
like that @electionlegal guy, if you scroll through his account its clear he's doing it as his full time job, and you'll notice BAP and others are either retweeting or commenting or posting about 100 tweets a day. if not way way more.
But by helping out people with the right takes and supporting their friends with the right takes it ends up making "normies" or anyone not paying attention like null to start going "i guess Jeff Epstein wasn't actually a bad guy, all those 19 year old girls consented" because they see posts about it from multiple people to the point it has to be true.
A great example of this is the idea that monkeys don't jack off in the wild and only do it in zoos. Thats complete bullshit, but because these guys constantly said it, people assumed it was fact. And much like Jews and the holocaust, these guys laugh at idiots for believing their lies.
