@RiseOne Well, I've heard that "do you even eat?" line they used as an example of bullying at least a dozen times. I wouldn't have called it bullying with the tone of voice in which it was said to me, though, not even once. Shrug.
It doesn't seem to be a bad translation. It's got a few typos and misspellings, but nothing that leaves you scratching your head. But yeah, this is what manga would look like without typesetters and their standards. :P
@Koin Q.E.D. isn't a reference to the TV series or anything; it's a term frequently used to mark the end of a proof. It stands for "quod erat demonstrandum," and it means "that which was to be demonstrated."
