Here is Frontier's residential and business TOS. Additionally here is a page they have on network management. There's nothing in any of these pages about throttling. They do say that they reserve the right to ask you to upgrade to higher tiers of service if you exceed the limits (they don't currently have any, to the best of my knowledge) of your current tier. Two interesting points from the network management page:
As a result of explosive growth of the Internet and the availability of ever more sophisticated applications, per subscriber bandwidth consumption has dramatically increased. This causes periodic congestion in the network that Frontier must address. Generally, Frontier utilizes a best-efforts approach to deliver residential High Speed Internet service. This means Frontier does not prioritize one type of traffic (e.g. video) over other types (e.g. data). Frontier seeks to deliver all traffic at the speed the customer has purchased (e.g. 1/3/6 Mbps download speeds); network management is content and application agnostic.
Frontier uses network management tools to enforce quality of service to business customers for applications that are sensitive to packet loss, delay or jitter like VoIP, time sensitive data, and video traffic.
