As a reader who's spend thousands of dollars on this site deleting reviews just puts me off your story. Writers who delete reviews for the stats are the norm and I avoid them. Like the author of the vampire novel deleted a crap ton of negative reviews once his story started getting advertisements on the app and readers with different tastes started reading and didn't like it.
Tbh basically all the authors delete any real reviews that have criticism. I think it was a mistake giving authors the ability to delete all reviews at will. It should have been way more limited. Idk any of the top stories basically delete reviews. Only translations don't give a fuck unless they're fan translation the contrqct where they dont get commissions for chapters and instead get paid by coins spent.
I know there was a problem with readers bombing negative reviews before and author would spam bad reviews at each others stories before it was implemented but now it's like reading fake reviews on Amazon or the app store. Just makes me think those authors are pathetic.
