Dude...he explained it to you that it's also other factors, and both CKtalon and MotivatedSloth pointed out that the highest number of fans don't mean anything if you have 200 "fans" unlocking just 1 chapter as opposed to 100 fans unlocking all 21 chapters. There is also the thing about bots (which often just unlocks 1 chapter anyway). You wanted clarification and an explanation, and they provided it to you. I'm not sure what more you want. Maybe in the past, it just turns out that the one with the highest fans also was the one with the most number of chapters unlocked as opposed to only one chapter being unlocked.
At this point, it just sounds like you're salty that your favorite title isn't chosen, rather than Webnovel "cheating" or being "unfair".
