Just got finished reading a forum that linked on reddit for a bot that I will not name here because apparently blizzard sent out a massive ban wave today. Let us just say that one poster on this forum had 7 account botting 24/7 and has made over $13k selling gold so I am pretty sure losing an account is not an issue whatsoever.
Let it be said I do not condone this and hate what it has done to the economy where we now see prices on items for 100s of millions of gold. Also it was said that only his botting accounts were banned and not his selling accounts so they are only looking for bots not sellers or just yet.
I hope they get a handle on this since the AH is integral to play that dealing with bots will keep regular players at a loss forever. Especially with players being able to buy/sell gold from botters on blizzards own RMAH they honestly just made it easier for these players.
I don't want to say too much as I'm pretty sure it's against the rules but the lowest the RMAH will let you sell commodities for is 25 cents a unit. Gold is in units of 100k and already sells for much less than that. Just like with any other super cheap item you're not going to want to buy it on the RMAH (I wouldn't buy gold anywhere, so don't think I'm advocating those sites).
I think for me my thinking is that how do you know that anything you do at any third-party site is going to be safe? You could get a virus, and certainly I would not want to do any financial transactions.
Correct, but it still doesn't mean that nothing can legally happen when breaking a contract. You won't have to pay a fine or go into jail (a matter of criminal law), but you can be forced to meet the obligations of a contract or pay for the damage caused by breaking it (a matter of civil law).
BTW, if you sell something for money to an extent which makes it a business, you usually have to pay taxes for it. That means, Blizzard can be pretty safe with banning thase people who don't pay taxes, even if the ban itself is a bit dubious. These people cannot take the risk to sue them or make any too loud demands, else their tax fraud might be revealed... and that's a matter of criminal law which might lead to prison sentences.
