Venus' observation is not wrong but she'll never get the tribe to go for that, especially since many of them already don't care for her. Her trying to go after Hunter will likely only make them want to get rid of her quicker.
A Hunter blindside is best saved for when they merge because I can for sure see her being able to sell to the other players that he'd be a big threat in individual challenges and he's very nice and has too many friends, so he'd be a social threat.
