That is why I am in favor of using a more advanced forms of captcha, and if an incorrect password is entered, require a time delay of five minutes after the third password entry attempt fails.
This is irrelevant as password cracking like this is used offline for password files/databases. Obviously for logins you don't need speed since the network alone would slow it down too much.
The OP already said he was joking just to see the reaction.
It's amazing how many took it seriously. Though people already offer similar services via Amazon EC2 on demand and it's a lot less costly.
