Spammers are going nuts.

http://www.virtualmda.com/ will pay you 5$ for sign up and then 1$ for evey hour your PC will send the spam using their spam bot running on your internet connection.

So my idea is to sign up, make a LAN of ~10 PCs + 1 firewall that will block outgoing spam and enjoy earning 10*24*7=1680$ per week ;)
Someone have to try this!

Moreover, as their services had just begun, they will probably will pay the money for the limited time until they will disappear.
