Bid Promising/Dirty Rushing?

[allthatglitters]

So my school, like many others I'm sure has a strict policy against dirty rushing and bid promising. Unfortunately there is really no way to enforce that policy, which brings me to the story behind this post:

A girl in my pledge class met a girl through a mutual friend and immidiately told that girl "I want you to be my baby!" She has since brought that girl to every single social we've had and introduced this girl to everyone as her "future pledge daughter". The thing is, this girl is very very average, but she interviews SO well and because she's been at everything a lot of girls know her.

She went through recruitment as a freshman and got cut from our chapter, so she's going through now as a sophomore and has her sights set on our chapter and only our chapter and seems pretty confident because a) that girl has been telling her all year she's definitely in and b) she knows so many girls because she's always in our house hanging out and at socials. My thing is, if you were cut once, there was probably a reason, a solid reason, and I don't think its fair that she's essentially playing the system backwards and going though again to get in our house and isn't really caring about any other house. I talked to an older girl about it and she said to trust the system, so I am, but is that "dirty rushing" technically or am I just crazy?
