Quadrille,

If you find something you can exploit, like the previously exploitable Twitter Bio Link - [mattcutts.com...] then you can easily write a "bot" that will create 10,000 twitter accounts in no time.

The only problem is that the captcha needs to be solved on each account creation. So you pay $20 to have the 10,000 captchas solved by one of the above services.

Your bot would try to register an account, take a screenshot of the captcha, pass it to the captcha breaking team via their API, wait for and get the result, and then pass it in with the other form values. Now you have 10,000 twitter accounts ready to give backlinks to whatever sites you want.

And obviously there are hundreds or thousands of sites out there where a system like this can be used.
