According to his user ID, this is the infamous Pawel Nowak, a gentleman that has been attempting the "I have antique katana to sell" scam for at least 10 years now. Periodically he will send out a flood of emails from various sword art related fora.
If you do a search for either Pawel Nowak or Pavel Novak, you'll find threads on here about him, as well as at any other sword art related forum.
Give him the heave George.
