The summary to all of this is: Does WN even give a ****?
Authors are free to delete whatever they feel like.
Readers are free to get mad if their review gets deleted, and repost.
Yes, it's sad that the effort of the reader in reading and critiquing goes poof at the whim of the author.
Webnovel's system fully allows this.
The question is: when is this back and forth too much?
Is it the author's right to keep their novel looking however they want? Hey, they could delete the whole thing if they really wanted to.
Is it the reader's right for his opinion to be seen by all? Regardless of how the content is perceived by the author?
There can be no gray area in deciding this. However, one person's honest thoughts could easily be perceived as another's trolling. It is subjective, so that's what makes it hard to fully go one way or the other.
At what point does pushing a person's thoughts on another become harassment? It doesn't matter what the review contents are anymore. What matters for those who judge is intent.
What do you intend to do by continuing to repost the review? Who's freedom is being imposed on? Is any party damaged by having the review not being there?
These are the things that you must ask yourself. These are the things the community decides. And maybe (fat chance, lol) if enough people think one way, then WN will change it.
