Apparently not... What's Fuffy?
Scott, for one, didn't have as big of an impact on Buffy as these three did, and for two, no one would vote for him.
Parker was never Buffy's boyfriend. She thought that he was, but he was in no way in love with her. And like Scott, no one would vote for him...
And about Satsu, I'm pretty sure Joss wouldn't want his main character, and not to mention ANOTHER girl being lesbain. If she ends up going out with her, okay, you got me, but I'm pretty sure she isn't gonna happen. (and she probably wouldn't be voted for over those three either 🙂 )
