My guild leader is a very strict WoW player. He's sort of odd, actually. He would kick me out of the guild if he knew I botted, even though I've been first or second on the DPS list, and first on the healing list. He believes that the game should be played, not botta. Basically, he's a hardcore believer in the EULA and TOS.
*shrug* So, I don't mention anything and I keep supplying the guild with mats, potions, gold, and assistance when needed.
On a different note, I believe in botting. If everyone did it then there would be no wipes, or at least they would be drastically reduced, but then the gold market would be non existant, so it's a double edged sword.
