I agree that there should be an element of risk. If Blizzard wanted people to be able to easily move goods between factions, they wouldn't have made separate auction houses, prevented you from buying your own auctions on the same account, or made it so that you can't mail items between your opposite-faction alts. The system is clearly intentional and not in need of fixing: goblins need to accept that they incur a risk by manipulating game mechanics to bypass these obstacles. I can understand a guide to minimizing risk, but I thought equating sniping to stealing and the inclusion of a "how to fix it" section smacked of a sense of entitlement, as if it's Blizzard's responsibility to ensure your mechanics-bypassing transactions are 100% safe.

Definitely agree with both of these comments. It's a huge "We do not condone this practice and will make it as difficult as possible without outlawing it" signal from Blizzard that you can't buy your own auctions with the same account. Trying to work around it is a risk, and there are people who put in time and effort to capitalize on that risk. The best way to get around it is mentioned in this post: put the item on the AH at the price for which you wouldn't mind someone else buying it. But if people don't want to spend that gold or don't have it on the toon they're trying to transfer it to, then it's on them if their auction gets sniped at a low price. It's not theft.
