It makes me wonder how the vetting process occurred before? Did they ever have fake accounts sneak through in the past? I assume there was some contact with the real person/celebrity/company, but could a disgruntled ex-PR rep for some celeb have created the account, and had enough secret info/credentials/whatever to pass the vetting and then start tweeting nonsense?
But the fact that the vetting process was completely halted is just nuts.
