I think it may have been sunny herself!!! Sucked us all in - good joke though! - if you look at it this way she got her log on names confused loged back in as Daniel and accidently replied as Sunshine? eg "Daniel" says " sorry daniel just friends, baynessy the one for me" Why would "daniel" be replying to himeself?
Just a thought anyway: If it's a crank, it's a classic, had me going!!
