OK, follow up on my South Africa "Hot Lead". Contacted the guy and he responded by doing a full scan on his computer - he was very cooperative. Ultimately reported that he found nothing on his PC, eventually he did a reboot or equivalent and his IP address changed.
So, turns out his ip address was dynamically assigned at initial connection – dead end.
I do appreciate his time and effort and gave him access back to my site.
