I'm not convinced that's the real Fiona Barnett on Twitter. My guess is it's someone impersonating her for the FAST following. One account in particular (see screencap) was tweeting out "Follow this account" to hundreds of twitter users including mine. That may very well be the impersonator.
"She" gained over 5000 followers in under 24 hours. I see no original content that would lead one to believe it's the REAL Fiona.
Plus I highly doubt she would go with a SUGGESTED handle (@fionaba47662575) when she could craft a much better one.
Heck, the account could be run by people who want you to THINK she's still alive.
Is there proof she's even kicking?
