That's true, usually pirate sites wouldn't be popular, but because of excessive release of free chapters which are usually not the case with legal sites, thus, this happened and honestly i think there are also other options to prevent this kind of thing to happen occasionally, i used to drop off mangas because of its slow update and honestly i think it's one of the reasons why author on legal sites Don't get too many supports. I just hope they would have any other ways to prevent this since people greed knows no bounds, they just do whatever they can to get what they want. This is such a good manhwa so i hope the author won't drop it and hope they will get better soon!
It happens like this:
Author spends time and energy making manga. Author uploads to a legal site waiting for income from said site. Buyers upload to illegal sites. Most supporters drop manga from legal site. Author starts to notice decline in income. Author now has financial issues as they aren't counting with the initial income/support they were receiving. Anxiety over paying bills and debts comes. Tiredness from spending time and energy in manga comes. And this later develops into depression, insomnia and anger, that such piece of shit people can think that they must go through worse to rightfully have depression. YOU DONT KNOW ANYONES SITUATION TO A 100% SO IF YOU DONT GOT NOTHING NICE TO SAY SHUT YOUR MOUTH AND BE NICE. Now please support the author with buying atleast 1 chapter while reading on illegal sites.
