I could therefore simply close this account (after my ebay fees are paid of course) and restart with a new account?
You don't have to close any accounts.
We can all have several accounts. I have seven myself.
Some members use one account for buying another for selling and yet another for posting.
Or two selling accounts for different product lines (like bibles and sexy lingerie). (Although I do find a lot of copies of Lolita and Lady Chatterly at Baptist rummage sales.)
