Yes correct I edited it because I remembered I've seen something of Cisco in the past. At first I thought it was a free project sponsered by Cisco.
But discovered it wasn't for a long time anymore. However if I contact them, mostly one very friendly guy who is also called Richard, is answering the support mails.
Haight is indeed correct in being amazed at "how long the site was kept alive, seemingly with few changes". It's a so simple setup and layout and indeed unchange for more then a decade (lets say from the start).
I didn't have too much issue registering, and on a couple of things which went sideways, that support guy Richard fixed it very fast.
Problem is we do need to fight spam. And as far as RBL's go, I still like this as one of the best, even if ancient. Haight created something great, imho especially for that time.
