Quest Load?

If I were to quest load and complete the quest for the Original Shadow Guard of Nulgath what would my chances be of being banned for it? I'm assumiing high but the quest is still doable.

Can you turn in the quest ?

it looks like its very very very old quest , i doubt u can turn in it

Haven't tried and thats my worry because IF I try to or IF i do I'm wondering if something will trigger and result in a ban or something. I'm sure it's possible to turn in being that there are still some people (very few) who actually have the Shadow Orb.
