If you are getting spam from chowda.net... I can assure you, it is NOT me! Some asshat spammer(s) has been using my domain as the reply-to address for their spam emails... it sucks for me too.. I've had this domain for over a decade and cannot abandon it.. hopefully they move on and leave me alone some day. I have never sent a single spam email to anyone.
