I thought Adwalled chapters were being linked along with a little padlock icon, but the chapters are disappearing from my reading lists like they are being deleted.
webnovel.com has recently instituted a requirement that you must log in before giving you the opportunity to access the ad-locked chapter. The ad preroll wasn't inconvenient enough for NU to block the chapters. However, requiring a user to create an account and log in to view content has long been against NU policy, so all ad-walled chapters from webnovel.com have been delisted until webnovel.com removes the login requirement.
So recently when I'm looking at NU I can't find any updates for some QI hosted novels like Reverend Insanity and Paradise of Demonic Gods. The latest for Reverend Insanity on NU is still chapter 349 while on QI it's already chapter 352. Could it be that this have something to do with QI latest update which forced readers to login in order to reaf adwalled chapters few days ago? Thank you.
In short, yes. An ad-wall that anyone can access is fine by NU's rules. NU doesn't list chapters that require a reader to log in before viewing them. Already discussed here: https://forum.novelupdates.com/threads/adwalled-chapters.68654/ Edit: Looks like the other thread and this one were merged.
