 :A fair question. My understanding, and the guideline I work to, is that an editor who creates an account with a promotional username but makes no edits is encouraged to simply create a fresh account with a more acceptable name. If, however, they have made edits and been blocked then if the block is imposed because of the content of the edits then creating a new account is block evasion. If the block is a username block and the editor wishes to retain his edits under a new username then he must seek an unblock to do so. If he wishes to abandon his edits, and as I say is not blocked because of said edits, he can create a new account without penalty. "
