Erudesu, dont worry! No one can be worst at translating than S2Manga ( ̄∇ ̄") Your translation skills are pretty good and enough to understand
1- their cropping is bad a lot of images are not full quality&full sized
2- they are not native English speakers so their grammar doesnt make any sense
3- they steal other scanlation's works
4- they are everywhere and they are not letting other scanlations to translate other webtoons
5- THEIR TEXT FONTS OOOOOOFF
