How To Determine The Origin Of Spam [/url]

Nice

Few months ago I wrote a small php script which can send (depenging on server) several thuosands emails per hour to any given address. Good thing for revenge, I only used it once to spam a guy from my country.
In his first message he provided a link to click on if I didn't wanted to receive more messages from him. I clicked and received more spam.
I think he received about 50 000 emails from me in a few days.
