Okay, so they are deleting a few hundred accounts every week, so what? You honestly think the RMT paid for the accounts? Odds are they are either stolen accounts or they used a stolen credit card to buy the accounts so it's zero loss to the RMT, they just steal another account or use another stolen credit card. They use their spam bots knowing they will be banned sooner rather than later, this doesn't help us who have to turn on /busy.

Prevention is better than cure, be nice if SE did something and put US back in control of our chat box so we can actually use it for it's intended purpose.
