AxL's Disclaimer from the original list:
"This compilation is an ongoing list of the DikuMUDs that have withstood the test of time. This is not meant to be elitist in any way, it is just interesting to keep track of where the oldest muds are running. If you feel there is a mud that deserves to be on the list send me mail and tell me. After all, I am sure that I may have forgotten one or two, or not know that one is around anymore.
However, any mud that does not adhere to the DikuMUD license agreement, regardless of age, will _not_ be listed. This has always been the case, but now it is stated formally.
Note: I do not have access or control of the copy of this list found at dikumud.com. I will try to get an update put there, but this list as posted to various spots around the internet is the official source."
"As of 2019, a lot of these guys don't show the banner required by the DikuMUD license anymore, as was required by AxL for inclusion in his original list. I'm not going to track down if they've changed code bases or what. These were all Diku based muds at one time, and they are still up and running-- that's good enough for me."
