[no dems]

As a point of clarification: swiftboatvetsareliars@yahoo.com is the e-mail address the threatening e-mails are sent out under.

if you start getting email from the bad guys:

abuse@yahoo.com

[gilliam]

Threats sent out via a yahoo account is a violation of their agreement with Yahoo. You should complain to:
http://abuse.yahoo.com/

I am willing to bet it is some high school kid.
