Quite. It isn't as if graduate recruiters have a shortage of good candidates to chose from, so not only do the successful ones have to stand out, they also have to avoid giving the employer a reason to choose someone else. I'm sure plenty of recruiters would have some sympathy, having done daft things themselves in the past, and would recognise a bit of silliness that went too far, but that doesn't mean they'll want to give her the job when they can easily choose someone else who is a lower risk. Of course, she ought to be able to put this behind her in a few years with some work experience, but will need to demonstrate a bit more humility first.
