Can I get banned for this?

I know a certain place in Icecrown Citadel (outside) where you can fly right under Northrend. Now, this is not a big bug, but if I use it to get inside VoA, can I actually get banned? I can tell other players that may ask how, so I wouldn't really gain an advantage over others, because we will all know about it eventually. WG's controlling is sometimes unstable and there may be times when some people like us can't get inside when the time needs it, most of us come home late, so this would make sure VoA can be accessed for 24/7. If not, I can understand it and I can lead you where that spot is in case you want to do something with it. But overall, I can't decide this, because this bug seems pretty tame and the player can't win WG anyway without breaching the gate first and I haven't found other places where this can be exploited as there's barely a ground you can stand on, unless we take into account that players can appear anywhere killing the enemy by the power of surprise, but they can be reported if they abuse it this way.

You can't enter the Vault of Archavon instance if your faction doesn't own Wintergrasp, regardless of any texture glitches to allow you to enter the portal room. You also get booted from the instance the moment your faction loses Wintergrasp. So unless you've found a way to allow the server to actually allow you into the instance, then it likely isn't of concern.

I actually tried it after you replied and now I feel dumb for even writing the comment. I assume atleast that going under Northrend is not bannable if I only go after some unreachable veins that are stuck inside the texture.

Just as a fair warning, I know of people who've been banned for abusing that hole to fight the other faction while they're trying to enter VoA.
