I dont think that rmah was gonna be a real option for people who brake the rules / dup anyway.
It seems more profitable from a business pov to sell on ebay than have to go through so many charges that the rmah has on it atm
Don't forget another reason people go to ebay is that you don't lose 15% from transfering to paypal. If you have earned 1k € and you put that on your paypal, you now only have 850€ left due to the cost of 150€ (which is 2days pay for some people). Which is a great motivator to use ebay.
