Internet providers on Thursday formally revealed their pacts with the MPAA and RIAA to curb piracy. The new strategy (below) used by AT&T, Cablevision, Comcast, Verizon, and others will first send "educational messages" to an Internet account if a music or video producer sends a notice of an alleged copyright infringement. If a content producer detects another incident, the notice will require a click through receipt that will prove they had received a warning and which could theoretically be used to sue the account holder for knowingly ignoring any warnings.
