They admitted to posting ads on the website on a regular basis using Scott's phone number. Police say the girls also admitted they usually get a hotel room for their customers.
Both suspects face counts of maintaining a house of prostitution, soliciting an act of prostitution, and the use of a computer to violate state late.
Police say they have made numerous prostitution arrests off Backpage.com.
