Novel readers who spoils everything in the comments, gets mad when the manhwa doesn't follow the novel, and then give a bad rating just because the manhwa is not plot-by-plot like the novel.

Wants everything green and boring.

Doesn't read tags and reviews, then got mad for finding bunch of rape and non-cons, flooding the comments in EACH chapters, AND still reading.

Those who justify giving a middle finger right on author's face because author gets angry at social media after knowing people pirated their series. We are all engaging in ILLEGAL activities, the uploaders, the translator teams, they are all aware of this. We are not supposed to consume someone's livelihood for free. The LEAST we can do is shut up, not reuploading screenshots everywhere, and accept if the author is angry. Stop fucking ruining it for everybody else!

Those who are not old enough to read an adult story but blabbering their mouth judging people. Yes, I enjoy reading toxic and morally-wrong stories. Why? You got a problem? Then fuck off and wipe your eye booger instead of foaming over me.

Those who suddenly replying to my old comments and trying to argue with me when I don't even remember the fucking plot. Before you move your fingers too fast you should use the brain more and think, "Am I starting an argument with this person because I know I will win, given that I have an advantage of freshly-reading this comic so I know I can pull out receipt immediately without having to reread the whole thing? That means I'm not looking for a debate, I just want to attack someone and it's such a shitty thing to do."

Those who cannot distinguish fiction and reality. No Janet, what's on your mind is not the same with your actual behavior in real life. Now ask this question to yourself, when you celebrate the death of a certain person, does that mean one day you will actually murder someone that you don't like? You think that someone deserves to die a horrible death, doesn't that automatically mean you're somewhat a non-offending murderer and you should be put on watch?
Normal people are capable of separating fiction and reality, and if you don't agree, that simply means you're not old enough to read such things. Period.
