premise: Robert L. "Rusty" White (born July 1945 in Newton, Mississippi) is the founder of the "Robb Report", a magazine he created while studying art at the University of Mississippi in 1967. "The Robb Report" was originally a newsletter entitled "Twentieth Century Confederates". White sold "The Robb Report" in 1983.
hypothesis: The Robb Report still publishes to this day.
reason: It's not explicitly mentioned whether it does or not, even if it was sold in 1983 it could still be published by someone else. It's difficult because the last sentence in the text probably tricks the system into thinking it must be incorrect.
