The only saving grace is that the Department of Home Affairs (of which the Film and Publications Board is part) is so incompetent that their reach exceeds their grasp, and it is relatively easy to circumvent their authoritarian tendencies.

Until recently many South African Apple device owners had Kenya accounts to buy games (including most educational content) because of the Board's refusal to allow South African App Store games without rating every game itself (eventually they relented).

Home Affairs, which also handles citizenship and immigration, is a mess, and has made the South African passport worthless thanks to rampant corruption and incompetence (historically anyway- corruption may be improving a bit, but the damage is done).

Their latest trick: to require burdensome documentation from international travelers with children ostensibly to combat child trafficking (because of by dubious data from a lobby group that caught a Minister's ear). It's expected to severely dent the Sputh African tourism industry.

TlDr: Even if these proposed censorship regulations come to pass, it is unlikely that they will have much of an effect thanks to the incompetence of the would-be censors.
