Note the words, ‘Social Media Exchange.’ There are sites out there where, for five quid or in exchange for retweeting a bit of publicity for someone (bartering), you can send out a message and remain anonymous: you’re hiding behind hundreds of accounts. These sites care nothing for you; it’s possible that the twitter account holders don’t even know what’s being sent from their account if it’s managed by someone else. We know that, because we contacted one; she was hesitant, but helpful. Trolls scare people, after all.
