People who tried to buy Twitter followers apparently had their accounts compromised in the process. So tweeters trying to fool the world were, themselves, made into fools. That's sweet, sweet social networking justice, right there.
Twitter Inc. is now requiring people who use follower-acquisition services to reset their passwords, according to ReadWriteWeb. Some of these people had handed over their passwords to third-party websites in the hope of looking more popular on Twitter, often paying a fee in the process. The password-sharing enabled scammers to send out spammy tweets from their accounts and to follow and unfollow other users on their behalf. So their attempts to acquire one completely imaginary good—a higher follower count—resulted in them being tricked out of a different completely imaginary good, Twitter cred. At least nothing of actual substantive value was involved.
