I think you hit them at a bad time. I think he DID have ONE very brief period where someone was using an exploit in the forum software to do some of that stuff. But it didn't last very long, he updated the forum software and that was the end of that. So I guess I can see where you might have thought that. But the site has never been abandoned. It's been up for as long as I can remember. It's not very fancy, as Ryandor doesn't play UO any more and he doesn't have a lot of time to make it all pretty, but it is functional. He's left the site up to support the community.
I created the punt file repository over there to preserve all of punt's utilities, which were hard to find after they decided to take the MapGen2 site down. Ryandor has been pretty much the Dragon support site ever since the Dragon site when down a few years ago.
Anyway, I encourage world builders to drop in to
Ryandor.com - Maps for UO Emulation and Half-Life as its still a great place. It's not very busy these days, but you can still usually get answers to questions and there is a ton of useful world building info in their forums. And also Orbsydia whenever they get back online, from what I have heard they have suffered a severe hardware failure and need to rebuild everything from scratch.
