I get soooo much of this. Please don't. It only ends up in /dev/null - usually without me ever noticing it. It just wastes bandwidth and it is really boring having to deal with this stuff. Honestly, what kind of idiots are responding to these stupid mails? The spammers are clearly making money doing this. People, please stop responding to them.
Use it. I have a GPG key and it is available on the GPG keyservers so get it and use it. Your mail is significantly more likely to make it through the spam filters if it is encrypted and/or signed.
