Anybody who configure his news acount with his real, un-obfuscated address is 
just asking to get spammed. My address *looks* OK, but there is an added DOT "." 
in my name. Remove it and you can send me mail, keep it, and the mail bounces.
Take note that news posting are keept FOREVER on google archives. I've found my 
firsts news posts there, they date back to 1997, with a real address.
