Hi, I've recently been using this as a way to keep prices low on items I want from the Black Market Auction House:
If you recruit the follower Tormmok , he is so large that you can position him over Madam Goya and make her hard to interact with, and impossible to click.

Followers generally stand to your left, so if you just turn to the right (from facing Madam Goya) and wiggle a little, he should move in the way.
NOTES:
quote from wowhead comments'You'll found him at 44.9, 86.9 in Gorgrond.
He'll probably be fighting some mobs, and you'll see him as hostile (red), though you won't be able to attack him.
Just kill wave after wave of mobs (it may take a few) until Woodfist appears. When you kill Woodfist, Tormmok will turn to friendly (green) and after a little talk, he'll offer you the quest to recruit him.
He is recruitable by both factions
There is a macro to still open Madam Goyas window if you lose it but don't want to move:
Just hit ESC and go to keybinds to find Interact With Target
Happy Sniping ;3
