[unknown] We don't really know what this is about except what you are trying to paint it out to be.
So we are now in the assumption that this is:
1) related to your mistimed Facebook Ad which did not follow the Facebook rules
2) You spam adverts in forums
3) The low review you got that showed Chapter 0 as read.
For 1) You were in the wrong though and I read that reply before in Webnovel FB GRoup. It wasn't really that harsh but, to each their own.
For 2) You have been doing this too excessively, so I suggest you tone it down as it is "too much" for a lot of people. There is a place and time for everything. Don't spam.
For 3) People do sometimes read without logging in. Then they reach a tipping point where they would want to review, so they login. When they do that, their status resets to chapter 0 if they don't backread to the last chapter they stopped at. Heck, people can go to the most recent chapter and immediately post a review to pretend to have updated themselves in the book before reviewing. That's how the system recognizes it. You could ask the reviewer until what chapter they have read for them to make such a comment, but you also mocked them didn't you?
You could also wait for them to respond, maybe a week, before reporting the review.
It's not even a big deal that you are making it out to be.
