WOW: Skinnin' for a Livin Guild Achievement Exploit

Skinnin' for a Livin is the Guild Achievement to skin 10,000 mobs.
This can be done semi AFK or with completely AFK with a button pusher. The mob will despawn eventually but you can get another one and spam your key to skin the new one.
I Tried this on grey mobs and it works as well, so I guess you can make a new char, learn skinning and get to work.

1) Go to your profession tab (P > Professions), grab your [Skinning] ability and put it somewhere on your hotbar.
2) Disable autoloot in the interface options menu.
3) Kill some monster you can skin and loot it.
4) Target the corpse and use your [Skinning] ability over and over.
