One very notable example of this is Dungeon Crawler Carl by Matt Dinniman. He's even just announced that he managed to sell publishing only rights to Ace for large scale distribution which to my knowledge is a first (from authors that started on Royal Road).

Also, I'd highly recommend reading Dungeon Crawler Carl if you enjoy anything close to Douglas Adams-esque comedic sci-fi. Its definitely trends a lot more "adult" than Douglas Adams, but that's about as close as I can think of off the top of my head for comparison. And I'd very much recommend the Audible versions narrated by Jeff Hayes for anyone that does audio books. The Sound Booth Theater production is also good but I'd only recommend that if you're doing a re-listen.
* there's a significant conflict between "this is a place to read stories" and "this is just a place to advertise for Amazon"
* the effective site rules are unwritten and quite arbitrary (one unwritten rule: you are not allowed to say anything positive about real-ish religions, only negative things)
* way too much pedophilia, including in site-promoted stories. Unlike religion, it's clearly not something they put effort into removing.
Royalroad is not a place you go to find objectively good stories, it's the place you go to enjoy your particular blend of delicious trash because in the end you'd rather read chapter 1600 of the long running braindead litrpg than you would whatever just won the hugo's.
Of-course readers have also gotten smarter, many now leaving 0.5 stars for all new stories. If they are banned later, you can still adjust your rating. So now many new stories get a surge of 0.5 ratings.
