@_Baal_ some webtoons on webtoon are translated from a other languages to english(like Tower Of God, The Gamer, Omniscient Reader's, ecc...)
I think (i'm not too sure) that korean raws (non translated comic/manwha) are taken mostly from Naver (korean vers of webtoon) and then webtoon translates them, in this case The Gamer" probably had problem"i with the translation of the chapters, but on Naver there are the raws, so in this case The scanlator took the raws on Naver and then translate it.
Then, about the coin thing, on webtoon, there are (almost alway, if there aren't in is because the series is paused or ended) 3 chapter that you have to pay if you want to read them (but if you only want to know if they have already translated you can see the chapter title freely), but, This is not the case, until webtoon doesn't officially release at least 1 chapter in the fastpass (the 3 paid episode) we'll never know if they have already translated the chapters.
(sorry for my english, i'm italian)
