An eye for an eye, a tooth for a tooth
The worst are the zoos but they aren't really "fail trolls" like the others, just despicable wastes of oxygen. I don't feel like they fit in terms of troll fails because they weren't really trolling.
The people nominated aren't the zoosadists themselves---it's the Farmers with mega-autism who tried to dox them by attempting to identify ice cream parlors and failed to archive important shit. I'm noticing there's some confusion over that.
