It has nothing to do with being blackballed. Most Oscar winners disappear after their win. The hype is dead, the movie itself wasn't huge, it was just Oscar buzz. You won Best Actor and Actress last year? The year before that? It's hyped from Dec to Feb, filled with movies that NO ONE want to see and the ones that does will see them only because of the Oscar Buzz. Mo was never a movie star, so why would she expect more roles when she spent two decades being the funny fat chick in Black films. . People did say that she changed when she won and got married. But look at Berry, what role has she been in that was huge? Sandra Bulluck? Porman? Only a few will take the award and still have a career, and most of the time they already had a full career before the win.
