Reporting Illegal Online Activity

I just received an email soliciting me to buy people's online identities. I'd like to report it to an authority, but I don't know where to go. Advice is very welcome. The email was sent to nine @brown.edu addresses, arranged alphabetically and clustered; it looks like someone was just going down a long list and broke it into several emails. The text of the message I got, with contact information removed, follows.
