Ice T has been recruited by a company called Robokiller in an effort to get even with scammers and marketers that call your phone every day.
RoboKiller is a program that answers calls from scammers and telemarketers, then the system starts playing lines of recorded dialogue in an effort to trick the marketers or scammers into thinking they’re on a call with a person. Now, they get to use dialogue recorded by Ice-T. They claim that its system has managed to keep operators on the phone for up to a half-hour.
The main point is to waste time that nefarious callers would otherwise spend scamming others. Another benefit is that it lets users listen back to the recordings, so they can entertain themselves by listening to a disembodied Ice-T chitchatting with unsuspecting con artists.
