I say this as both Kouhai's friend and a scanlator myself...
I don't think any scanlator is above criticism, no matter how much effort (or lack thereof) put in to a release. Seriously, there are many times where I wince at poor translations or typesetting, or anything of the sort. I honestly wish more people really would criticise scanlators (and especially myself!) because it's the only way people are going to improve. Kouhai knows well the pedantically high level of quality I hold myself and others to, but I think she appreciates it (mostly).
But there's good ways and bad ways to criticise people. I think everyone can agree that candy is showing us a really terrible way of doing so. And it's unfortunate, because not only is he actually willing to criticise where most aren't, he's causing a defensive reaction from others, including the awful "scanlators are above reproach" type of response.
We should encourage people to get better, not put them down... Or alternatively jack up their egos such that they don't see improvement as necessary.
The problem is some people are inclined to troll and over criticize....
Me im just happy for translations because...well, im fairly certain I could learn to speak japanese if I tried but the idea of learning to read it...well that sounds incredibly difficult...
So yeah, mad props to all the translators, editors, and such! ^_^
