Need a bot made that will sign up for accounts at digg reddit stumble and a host of other places using generated data with the option to include a username and to specify the email of where the conformation emails will go. After it signs up to these places it has to be able to bookmark a list of sites. It can then sign up for new accounts *Using a different email of coarse* then vote up said bookmarks or rebookmark them.
