Palantir may be engaging in a coordinated disinformation campaign by astroturfing these news-related subreddits: r/world, r/newsletter, r/investinq, and r/tech_news
Setting aside the veritable TITAN-loads of shady shit Palsntir is up to, it's also worth noting that Reddit's policy changes have made it clear that providing a platform for the spread of disinformation is a central part of its current business model, so I'd assume that not only is Palantir using it for that purpose, but that they are far from alone.
half of its already bots, so im not surprised and it usually the propaganda bots keeping up the engagements. Also i heard reddit wants to make thier post/account history mroe private so its harder to discern a bot.
