First it's a great way to practice your story writing. Instant feedback, and a way to measure impact.

Second, it's to create fake accounts with real post histories so that they can be sold. There is a lot of strategies and work behind this approach.

Sold accounts then look "real", so when real people endorse product X on r/buyitforlife or AskReddit threads about "what product's quality has gone down?" it looks like actual people and not a targeted marketing effort.

Long stories also make for good consensus building by hammering points that are relevant to socio-political discussions. Like when the Woke was riding high during 2016-2018 there would be constant discussions in r/relationships, AskReddit, TwoXChromosomes, etc. about abuse, to keep people constantly talking and thinking about gender issues.

You can also create "tailing" or "follow-on" accounts that post replies to the obviously BS stories, including those that post "lol what a load of BS", as that builds their history, too, and you can steer opinion by having a few of those supporting shillbots make outrageous claims for (or against) the story, and then disprove them in ways that leads the audience into intellectual positions that the posters want.
