The facts themselves are not subject to copyright, although if some business decides it does not like how its TOS is being violated it would probably stuff a few "fake" entries in there that would be returned to IPs that trigger a spider warning and then later go back and see if they were put into the db; if so you go after aggdata for violating a copyright on the collection as a whole. The data being provided by the businesses that are being scraped is not much different than that provided by a map service provider or phone book provider -- the individual facts are not subject to copyright, but the collection as a whole is and if aggdata is basically doing the web equivalent of photocopying a phone book and selling it to you then they are open to attacks from this vector.
