Technically couldn't someone download the bot prior to purchase and then reverse engineer it and figure out how we are using it on blizzard servers to bypass warden? I honestly thing bossland needs to make these forums private to only subscribers and not the open public.. as well as the downloader.
You can do a google search and see that blizzard requires all their employees that may touch proprietary info to sign both an entrance and an exit NDA. Additionally, what's the point of a mole if they aren't gathering insider info? So yes, a mole hired by the HB team would fall under corporate espionage standpoint (at least from that standpoint, I'm still not 100% positive that that's the correct legal terminology for this situation).
