if you read bl manhwas, it’s the three groups that always fight to release a chapter you can usually tell it’s an ai group / machine translated if they keep getting the genders wrong.
A few examples that i personally think are ai groups or use machine translations are paradise scans, desire scans, maybe kaizen and myth toons. I think I’m missing a few more, but these groups post readable but blurry chapters that when you compare to official translations or human unofficial translations, you can see the difference.
I usually identify a scanlation group by their opening panel. If they have people’s names in their title card (like how flame scans or reaper scans did it) they’re probably done by human translators. Another key factor is how they interact with the users here (like if they leave any tl notes or any memes at the end/beginning.)

how are these ai scans still shamelessly posting chapters everyone alr knows
