This seems a bit odd to me, having lived in South Africa at that time. There's almost no way a guy at home would have had that kind of access in Apartheid South Africa to the internet back then. There was access, but it was through big companies or academia and on a very controlled level.

Here's a quick rundown of internet access in South Africa during that time period from Wikipedia. From experience, it is accurate.

> The first South African IP address was granted to Rhodes University in 1988.[1] On 12 November 1991, the first IP connection was made between Rhodes' computing centre and the home of Randy Bush in Portland, Oregon.[2] By November 1991, South African universities were connected through UNINET to the Internet. Commercial Internet access for businesses and private use began in June 1992[3] with the registration of the first .co.za subdomain.

You might bring up stuff like BBS, but that was not around in South Africa until after 1990 also. You could technically have imported hardware and connected to a BBS in USA, but the costs involved and control of the only Telecoms operator allowed in Apartheid South Africa (Telkom) would have been unaffordable. Especially for Krugersdorp. I doubt you'd get some kind of USA led local police raid for pornography in Apartheid South Africa either. The whole thing would need some serious evidence.
