I didn't log in for a while and my account was deleted circa 1999, I was pissed, since I'd had it since about 93, although there was little I could do about it. What a great mud though. :)
I only discovered it around 2012, so I never got to see it in its heyday. I had great fun programming different things, though I haven't found the time in a couple of years. I still log in occasionally just to wander around and marvel at things--there's all sorts of weird stuff lying around, though I can never seem to find something when I go looking for it. I don't think they reap accounts anymore, since there's no longer a massive influx of players putting pressure on the database.
