By leaving negative ratings for accounts likely to wish to sell their signature, she is reducing the number of potential sellers of signature space, increasing the value of her signature space.
By jumping into the ocean, there is a chance I could create a tsunami too.
That's quite a grasp, even for someone like you.
There is >an entire screen worth of negative ratings left by Lauda that Lauda is not even attempting to say that they are scammers but are trying to sell their signature space.
Lauda is also very inconsistent in who gets a negative rating and who gets a neutral rating as he is leaving both negative and neutral ratings for the exact same activity, that reasonably does not warrant a rating at all.
Lauda is stretching the definition of who deserves a negative rating to much farther then who even trolls leave negative ratings for (let along anyone reputable) and all of the additional people that Lauda is leaving negative ratings for generally want to sell their signature space.
