I'm having problems loading pics due to a shitty Internet connection at the moment, but if there's no other plants that your worried about getting pollinated, you could always try picking the balls off. You'd have to be diligent, and get them before they pop open though. Even if you miss some, I'm sure you'd still manage to get some bud out of her. Mind you it'll be seedy.
If it were me, I'd keep her around... I can't bring myself to give up on the little things.
I have two other budha purple kush right next to her and I'm also germinating a CH 9 aroma that will eventually be in there vegging alongside the autoflowers...absolutely cannot have any seeds the only reason I posted this thread is because someone on my grow thread suggested that they might be false calyces and not pollin sacks.
GB, that is absolutely most definitely beyond a shadow of a doubt hermie bro. If you are worried about seeds you best remove he/she gently and take it far away from your grow op.
