Twitter has put out a relatively lengthy blog post effectively denying that any of the recently leaked, scraped or exposed data (mostly email addresses) came from its systems.
"We conducted a thorough investigation and there is no evidence that data recently being sold was obtained by exploiting a vulnerability of Twitter systems."
My only thought is, who is even left at Twitter to carry out a investigation?
