Pink wards exist. It's annoying, but that 125 gold is more than paid for with the kill gold. You also can just keep her in check by harassing her early - zone her and she'll have to farm with Q, which wont be up for every CS and if she's using it that way, she's not using it on you. Just keep tabs on her, and don't play stupid - if you give her breathing room to roam and snowball, she will.
