You are right, I had a much older account.  I have been buying and selling on ebay since they began.  I cancelled my old account due to an unfair neg fb from a scamming bidder that ebay could/would not remove.  I stopped using ebay for a while because I was disillusioned with ebay in general (policies, fees, etc.) but I started a new account because it's hard to stay away from ebay.

You are also right about leaving neg fb for NPB's, I never did it because I didn't want to risk getting it in return.  I still think that the option was enough to deter some NPB's though. I do have all the necessary/available blocks in place but that doesn't stop the problem.
