This makes things sound even fishier. I think there has to be something else going on we don't yet know about. The amount of money this scam will actually earn the hacker is tiny compared to the potential of this hack and yet they still have enough money left over to bribe a presumably highly paid Twitter employee? Or maybe the Twitter employee is a low paid person which leads back to a question I raised elsewhere in this thread[1], how many people at Twitter have the power to take over these accounts unsupervised? Whatever the number is, this hack is probably an indication that it is too high.
