Tbh, I think the free pass gained from voting with energy is to blame as well.
If I look at my personal habits, I read only fanfics and the occasional trial on here. That means that I have no use for any of the paid services and only the occasional free pass.
The result of that is that when a trial is sufficiently interesting to make me use free passes while they're up, I will often just vote randomly in the energy selection.
Usually that's the top female options but occasionally I take the effort to select the male lead books and select the topmost one there.
In this case I recall voting for a book about a bank in the title without a care.
I think I'm not the only one who vote randomly without being interested, just for the free pass.
After all, you don't need to have read or finished a trial you vote on just to vote on it. Which means the system mostly just encourages farming it for passes, as few people would otherwise vote on something.
Hense, most votes means very little as the moment the trial is gone, the book is removed from people's minds for being gone too long even if it does get translated and people will have lost their desire to read it again.
I think the whole gradual release system is inheritantly flawed anyway as it effects the quality of the authors publishing directly on here due to the way it works, but that's a topic for a different thread..
