If those users are legit, sure. But lets be honest...writing bots in Reddit is stupid easy. I have done it myself. Most things that appear on the front page are most likely not legit. Darknet Diaries, a podcast on hacking, had an episode proving how Apple Podcast top 10s are rigged through bots. Episode 27, specifically. And the thing is...if we can easily do it by pushing mediocre podcasts to the top of a list, why can't we do so with Reddit posts? The API even has calls to upvote/downvote posts and leave comments. This is a thing that Reddit as a company actively supports.

I highly recommend watching two videos..."The Dead Internet Theory", by All Time, and "Reddit is Being Manipulated by Professional Shills Every Day" by Point. They go into how Reddit works algorithmically, and how there is a strong incentive for corporations, governments, and political movements to write bots to manipulate karma. If hackernews lets me, I will link both of them and the darknet diaries episode. Im new here, so Im not sure how links work on ycombinator.
