In the last update to the app, the top 3 or so comments appear at the end of the chapter. I am hoping the developers can undo this change.
There are some readers who consistently post future spoilers, and somehow the spoilers get liked and end up in the top 3. Some comments are not much of spoilers, such as when a WN author already post spoiler in the next chapter's title. But some comments are blatant spoilers, like revealing the identity of a mysterious character, or the death of a character and the chapter number of when it will occur. I try not to read the top comments at the end of the chapter, but I have to scroll past them in order to get to the "Vote with Power Stone" button.
If removing the top comments isn't possible, then perhaps there can be a way for readers to deal with spoilers in the comments. Such as having an option for a reader to report a comment as a spoiler, and after a certain number of reports, the comment would have to be tapped on to reveal it.
