He just deleted about 90 one-star reviews and roughly 750 comments. Most likely because all of them pointed out that he is a thief and didn't actually write a single word himself in all his miserable life. So while I wasn't here when you originally asked this question, I would say that yes, he probably just deletes all negative reviews routinely, considering that that's what he's done this time as well.

It's much appreciated and have a good day!

Easy: just read anything by the actual author, most of it is far better than even this stolen story. Just search for TheBlack'sResurgence on fanfiction.net 😉

I'll make sure to let the author know your sentiment, since this is unfortunately not him. 🙂

... That supremely awkward moment when you steal a story from one of the most famous fanfic authors in the community, webnovel refuses to take it down even after having been informed of the theft several times, so now the nearly 4k discord members of the actual author are bombing your comments, reviews and ratings. Yikes. Sucks to be you, mate

Yeah! Amazing work at stealing a story! Totally worth an award! No, wait, that's not the word I was looking for... Prosecution. Prosecution was what I was thinking of 🙂
