Re:Twitter bug: Make anyone follow you on Twitter

As far as I'm aware, it's a feature that's meant to allow users to accept followers by text (there's a separate interface on the website for accepting follow requests). The bug is that it didn't check whether those people had actually requested to follow you. That's what articles on the subject have indicated, anyway.
I assumed that it was more of an intentional 'backdoor'.
