Verizon Communications and AT&T have joined up with service providers to create a "six strikes" warning system to address pirated downloads by their customers. Under the Copyright Alert System, media companies will monitor online traffic via a third party. If pirated material is found, the alleged violator will receive a series of warning messages. By the fifth warning, the ISP may choose to drastically slow the user's Internet speed. Users are able to contest the finding by paying a $35 fee that's refundable if they are found to be in the right.
