I can name Desire Scans, Paradise Scans, Mythtoons and Kaizen quite confidently as the main perps when it comes to this. They are using AI to translate low quality scans they find online and charging you for it. That's why they don't care if they're the only ones uploading here. Their goal is just to get people to go to their websites and pay. There are legitimate scan groups who offer early access for cash, but it's usually quite obvious when a group of individuals is behind a group.
THESE UPLOADS ARE ADS FOR THEIR SCAMS. DO NOT FALL FOR IT

is desire scans waging war on other groups this is like the 3rd manhwa in 2 days where they double upload after another group, fucking annoying
