So i just chose two at random now and they don't appear to be predatory journals, just journals with Impact Factors lower than 1.

Imagine to retract automaticaly all papers that confuse "then" and "than".

My English pronunciation is so bad that I'd never confuse them, but I see that mistake quite often.

This isn't a mistake though, right? These papers were authored by a chat bot, so why would anyone assume that any of the conclusions are legitimate?

This is the 2017 article with the typo https://jfisheries.ut.ac.ir/article_74390_fa7bb4e3378a7fa45e...

This is the bad translation https://jfisheries.ut.ac.ir/article_74390.html

They probably reviewed the original article in Farsi, and nobody took a deep look at the translated abstract.
