If you ISP is Comcast or AT&T, you should know that they are both working with the RIAA against you. Both companies admit they are beginning to send out warning letters to users who the RIAA believes are downloading pirated content. The warning is that the alleged downloaders might be disconnected from the Internet. All based only on the claims of the RIAA. Outrageous.

In December, the RIAA, the lobbying group of the four largest recording companies, announced the group would no longer pursue an antipiracy strategy that focused on suing individuals, but rather would seek the help of broadband providers to stem the flow of pirated content. The RIAA said an undisclosed number of ISPs had agreed to cooperate but declined to name them. In January, CNET News reported that AT&T and Comcast were among the group.

Sources told CNET on Wednesday that a Comcast executive confirmed that the nation’s second largest ISP is working with the RIAA. At the same Nashville conference where Cicconi spoke, the Comcast exec said the ISP has sent 2 million warning notices to customers accused of infringement by entertainment companies. The sources have also confirmed that Cox is a member. (You can read more about that here: “Comcast, Cox join RIAA antipiracy campaign.”)
