Everyone seems to have forgotten Operation Flea Collar in Florida 2002.  LE spent most of a year cultivating leads.  They tracked providers and clients by their emails resolved to the isp and user physical address.  They went through trash cans and reconstructed notes.  They wrote down auto tag numbers at meet and greets and determined who the owners were.  They subpoenaed apparantly innocent documents completely unrelated to the adult industry.  They posted fake escort ads.  They turned clients into informants.  They turned escorts into informants.  Clients and escorts were incredibly careless which made it even easier.  The amount of time and money spent was unbelievable.  So if your question is "would they waste their time?"  The answer is YES!  All of this is public record.  Do an internet search.

well if she's a college girl and not a pro, she might actually want to get to know you so she can sleep at night.

It's still pay for play, even if it's for books and tuition.  If this is really interesting to you, I'd meet for a cup of coffee first and scope out the situation.
