[quote name='RedRingOfDeath']They are not as tech-savvy or as well-informed maybe? Or maybe they dont want to violate Blizzard's terms of use, like hacks do (I dont think their terms prohibit powerleveling, heh)?
Look on eBay and you will see people doing exactly this: paying for stuff someone got for free. Look at the CAG marketplace and you will see people trying to sell/trade stuff they got for free (ex: pax trashball cole plushy, kinect helicopter prop from computerbilde.de, etc.).
Not everyone has the same information and is as well informed as others are. Just because I know that I can hack the game and get a lvl 60 doesnt mean Joe Blow in Arkansas does... Maybe that is why he paid someone on the internet to powerlevel him (since we are being hypothetical and all)...? Or again, maybe he is choosing to pay to get powerleveled because he doesnt want to violate Blizzard's terms of use (which is a valid concern if you dont want to get banned).
Not trying to be rude, but it seems that you need to start giving your arguments a little more thought. Just because you "know" something doesnt mean everyone does...the reverse is true also.[/QUOTE]
Use of your account by anybody that's not you IS a violation of Blizzard's TOU. It does, however, have a much less likely chance of your account getting banned since there's no cheating for Blizzard to detect.
I think that people do it because they think that Blizzard has effective anti-hacking tools, and that's Blizzard's best chance at keeping the game well-protected from hacks. Diablo 2 was a game notorious for being easy to modify. Blizzard would find it in their best interests to make it seem like Diablo 3 is pretty damn hard to hack and cheat in multiplayer.
Sure, people are going to crack the game and play it offline, or crack it and play it on private servers, people are going to do that and it's pretty damn hard to stop them, but to cheat while playing the online Battle.net version of it, that doesn't sound too promising. And that's the trick: if people think it's a risk to their accounts to hack the game and play online, they won't do it, or at least most won't be willing to take that risk. That's Blizzard's goal, and that's why the constant internet connection is a good thing, because it will make people think twice about cheating.
And paying for an exclusive con-based item, that the con-goer got for free, doesn't sound that stupid if you want it. Value is in the eye of the beholder. I could sell the Blizzcon pet I'll get this year, but I'd rather keep it over the $80 or so I could probably sell it for, judging on how much last year's pet is going for on ebay right now.
