does anyone know how to automate votes for digg? software maybe?

perhaps a bot to help with this? i will buy if i have to. what is out there that can help?

There is a guy on thsi forum selling this bot. Check out threads from Arby Dee2.
But i'm not sure of the stability of his bot because i've heard somewhere that there is some sort of Digg voting algorithm that only requires a ratio of Diggs from friends accounts & Diggs from stranger accounts.
I'd be interested to hear of anyone elses thoughts on this.
