Below is a thorough interview with the artist and her tweets:

"Mingwa: The act of freely viewing manhwa on illegal sites greatly affects my economic situation. I only publish BJ Alex, which is available only on Lezhin. In other words, Lezhin coins are my sole source of income, and I don’t get a single cent from users reading BJ Alex for free on illegal sites. The income from coins is fair payment for the labor that goes into drawing the manhwa. I need an income to live a normal life and draw in a better environment. If there are more users of illegal sites, I might not be able to work.

futekiya: Can you explain your work process? How is the environment for creating your manhwa?

Mingwa: I post one episode per week, working six days and taking the seventh day off. Aside from eating and sleeping, nearly all my time is devoted to work.

Most of the Korean webtoon market has a weekly release schedule. There are also more creators who work all week than those who can take a day off like me. We work very long hours but have yet to be paid fairly for them. This is why revenue from paying readers is vital in the Korean webtoon market."

Quote from Mingwa

I first learned of this from a fan, and also knew some of them were reading my manhwa on illegal sites instead of Lezhin.

Wait, as in Lezhin Comics?

Quote from Mingwa

I only publish with Lezhin in South Korea and English-speaking countries. If you love my manhwa, please purchase it through legitimate means from Lezhin Comics.

Yep. There's a likely possibility that she's Megalia.

Quote from Gookanon

Lezhin Comics
-Behold, the capitalistic central hub of Daughter of Megalian movement.
You probably heard of this name once or twice. All shit started afer Nexon's contract termination, when Nexon's internal Audit/Inspection team found out that the money from that t-shirt goes directly to convicted sex offender of 5 years old, and various other convicted criminals.
-Soon after majority of their webtoon artists declared full-support of Megalians and preaching about how great and holy the gender war is on their social network. But unlike Nexon, Lezhin never purged or made them to shut up. Inside whistle-blowers reported the high-rank of Lezhin Entertainment, are at least Megalian sympathizers and their editors are DoM members. Even their subscription numbers declined over 20% but they never aplogized, terminated contracts ever. They even double downed and threatened their readers for lawsuit, if they keep interrupt their business through boycott.

Quote from One Angry Gamer

For those of you who don't know, Megalia is an infamous misandrist group in South Korea, and has actively been ranked as one of the top 10 most offensive websites in South Korea. According to the Korean Times, the govermment has had to have multiple offensive and objectionable posts promoting acts of misandry removed from the Megalia web portal.

So, her struggling for money probably has nothing to do with illegal sites. For those that want to know more: An Incomplete list of all Megalians among us
