Such a measured response. Bet that feels good.You turned your "criticism" into a personal attack, and complained about effort and expected it to look like someone who's done it for years. That's not what we need here, and not something more people should be doing. That's just being a dick about it. There were others who provided real, constructive criticism in this thread. Maybe you should learn from your betters like you say this scanlator should do? Take your own advice?
I could have suggested that they look into typesetting resources and fonts. Or suggested that they do even a basic proofread of lines that don't make sense, or character names that are clearly wrong. Or scan the pages for any speech bubbles they missed to translate. But I didn't feel like it, because someone would inevitably have commented that they did an amazing job wow thanks so much for picking this up again man don't listen to the rude guy who told you you didn't do things his way you totally rock!
To me, there's no difference between constructive criticism and an insult. Both are met with scorn by different groups of people; the latter by people with holier-than-thou attitudes, and the former by the masses who would be happy to scrape their scanlations off the sole of someone's boot and consider it a slight to even think of suggesting that people do something to improve themselves. You literally cannot win.
Either of the two should make the person the critique is directed at think of how they could improve. Maybe the former is a tiny bit more helpful.
I don't think there's any common ground to find here, so that'll be it from me.
