Let's at LEAST give him the benefit of the doubt until he actually does something that could even remotely be fraudulent, like say, an actual sale offer! What's it hurt us if he turns out to be a fraud and says he's going to sell us something and then never takes anyone's money???
AND, I have been known to use colourful phrases like Greetings All, and Cheers, and certainly I am no Brit! (despite my last name)
Besides, I would gladly shake the hand of any former C='er, and I'm sure I'm not alone.
