There is no way I can link to any site related to spam.

Why should I believe anyone who works for spammers? If someone feels guilty for doing such job, why doesn't he quit? What about clear conscience of such people?

I don't really mind receiving spam messages. On the contrary, I'm very glad to receive such messages, 'coz I delete them every time without even reading them. Spammers just waste their time and resources when dealing with me.
