What?
Someone honestly trusted webnovel to moderate their ranking system?
HAHAHAHAHAHAHAHA.
Sarcasm aside, yeah, no. Do not in any way trust webnovels ranking/review system. Much like their contests, competitions and so forth... everything is influenced by spam, bots and BS. Trust none of it to be held to any kind of standard cause to be honest, webnovel just doesn't give a flaming rats ass.
