I really don't care if you advertise on the chapters but don't put shady redirect ads, ads with sound that pauses something the reader is listening to, and pop-up ads, or any kind of ads that interrupt a reader. If you want to put in an ad I would recommend for the app putting in an extra page with advertisement at the end of the chapter and for pc put static banner ads before and after the chapter so the text isn't broken up.
The term bonus is vague, many of the novels can't even pump out the promised chapters/week, right now it just seems like the most recent chapters will be behind an adwall, which is fine, but don't present them as bonus chapters if they're not. A true bonus chapter would be having say an extra chapter every 10k ad views or something.
If i can read a bonus chapter just by watching some video, it's acceptable for me. But the terms for this bonus chapter is somewhat vague. Anyway, "there's never a free meal in this world 😏" so this upgrade can help me to support translator team as well as QI. Just don't makes things too complicated. I hate complicated things 😑
