All the major scanlation groups use AI. Kaizen, desire, mythtoon, etc. You can usually tell when there is dialogue that makes no sense, especially if there are pronoun confusion (because AI doesnt understand context). It's also usuallyabout speed; officials or independent translators take a long time because its a ton of work whereas AI groups can crank them out. Look at the popular stories rn and you'll see these groups are ceanking out translations by the hundreds. Also, for profit scanlation groups try to lure you to their websites where you pay them for their translations rather than pay the original author.
if a group ever tells you to visit their website for more recent (paid) chapters, it's an AI group. actual scanlators have morals and standards and realize charging money for pirated content is so much more subject to litigation. like i just know lezhin and whoever WISHES real scanlation groups would charge money for their scans so they could easily sue them lmfao

Why it gotta get uploaded by a stupid AI translator
