Yeah, it's insane. From what I understand, they probably have a list of positive feedback comments that they randomly pick from. What's weird about it is that they live in this uncanny valley, where the feedback is very detailed but just vague enough to tell me that it's just an automated response. I got one comment recently that had especially given me the creeps and it goes like this:

If you have some great stories like this one, you can publish it on Novel Star, just submit your story to hardy@novelstar.top or joye@novelstar.top
How crazy is this?!!
