I am a huge fan of "sniping"; in most cases I think what people call sniping should be done more often. I am really bloody sick of decent series being abandoned and never completed because some confluence of douchebags and ridiculous "standards of etiquette" means that a series is monopolized, stagnated, and finally killed off because by the time other groups are "allowed" (fucking hell I hate that word in this context) to scanlate it it's too damn late. Usually because no good raws can be found anymore.
On a more general note, I'm highly contemptuous of the frequently mindbogglingly stupid shit used as justification to destroy scanlators. I forget exactly what flavor of weasel-speaking fuckery was used to do it, but I'm still salty over Don's Adventure in Another World being shut down, such that the only scanlations that can be found are shitty machine translations by lazy-ass rat bastards who can't even be bothered to keep chapters in order.
