I can tell you it is not worth the hassle or the money, I was persuaded to sell my account after i said no about 3 times.
The aftermath, within months of selling it the buyer got into bad standing and Ebay still link the accounts even though it was sold legally as a business and all the details were changed.
They used this as excuse to drop my selling limits to £500, this lasted for about a year of me emailing every month to complain, eventually they lifted it and after half a dozen times of me telling them its not me, i sold the account and someone else is in bad standing.
It all felt a bit like they were pissed off i had made money off the back of them. I wouldnt recommend it.
Luckily for me as i Trade for other people i just set each of them up with an account/s. I don't sell on my own account anymore its not worth the hassle, and i live and breathe Ebay ask any of my friends!
The way Ebay has been going the last 10 years is down, down and further down.
