Anvil,You think that after he decides not to talk to you anymore he will go into his address book and delete your name? He knows your voice and the tough questions you ask make him uneasy...lol He must of told you if you not happy sell?
What he decides to inform everyone about can't be anything relevant otherwise he has to PR it.
You think this is done one by one, One click and everyone is sent same email.
He also could be testing the waters and see what kind of reaction volume wise he gets with a little hypejob!
