VFD: our coveted place of worship where we try to appease the gods by crucifying that sacrificial lamb which is a crappy article. And really, that's all that VFD is. The name, votes for deletion, speaks for itself. We have a vote to see weather or not to delete an article. But in this day in age people seem to forget that. Users go around, doing unspeakable things on VFD. Awful things like talking and cracking jokes. So just as a frame of reference, let's just say VFD is not:
So there's this user, he did something to you. Let's say he voted against one of your articles on VFH, what a dick! So how can you get him back? I know! Why don't you nom one of his articles for VFD? That'll show him. What a great idea!
Instead of affecting him negatively, it'll probably backfire on you. Getting you a one way ticket to ban-land, causing unnecessary trouble and basically just making everyone angry at you. So just as a general rule, try to only nom articles for VFD that are genuinely terrible.
VFD is one of those places that just seems to attract arguments. I know that jerk who voted delete on your article really deserves to be told to go to hell, and that if you were the one lucky person to tell him that the world would be a better place. But here's the thing, no one fucking cares. It may also get you a ban.
So if you've never read Uncyclopedia's three rules, why don't you go take a look at the second one? Exercise that while you're on VFD and you should be alright.
Oh my fucking god, are we tired of that joke! In the words of the VFD rules themselves: "Please don't nominate Main Page or Votes for Deletion; that joke has been done so many times we might just beat you with a nail bat before we tear our hair out in frustration." Truer words have never been typed into a keyboard in all of history.
Of course it's not limited to VFD and the Main Page, there are a lot of things that you shouldn't nom for VFD (QVFD, features, the dump, etc.). So when nomming things for VFD, use common sense.
And if you do nom something for VFD, like... say... the UnNews main page, and you get in trouble, don't be a smart-ass and say "Well there's no rule that says I'm not supposed to.". Just say you're sorry, and move on.
