New Spam.

I have noticed that some new sign ups have as part of their Email Addresses ,what can be considered spam. One instance is the newest fellow, Dự án mới who has Giahuyhotel @gmail for an addy. There is just such a Hotel in Saigon, now ho Chi minh City, Viet Nam. I have not banned this or the couple others who have used this, as it really poses no threat to the site, but just wanted to point it out. Pretty feeble spam though.
