How do people create fake followers on twitter?

[Windowphobe]

Twitter isn't fussy: if you send it a non-duplicated name and something resembling a bio, it creates an account. There are code generators to spit out this stuff, and it need only be shuttled through the Twitter API slow enough to avoid attracting attention.

The fact that (1) this exists and (2) Twitter likes having the extra user names for boasting purposes tells me that there's never going to be a crackdown on this sort of thing.
