Best Mystery Minecraft Servers

Autcraft is a whitelisted Minecraft server for children (and adults) that have autism and their families.
What this means is that if you or a family member has autism and you own the computer version of Minecraft, you can register and apply to be put on the whitelist and play with other people just like you. Waiting time for assessment of applications is approximately 1 week.
Autcraft was created by Stuart Duncan (aka AutismFather in game) who not only has autism himself but also a child with autism as well. The server is administrated by adults that include autistics, parents of autistic children or a family member of someone with autism. There are also “Helpers” that include “jrhelpers” which are children that prove to be responsible, positive and helpful with people; and “srhelpers” which are adults that demonstrate some knowledge of the game as well as being respectful, responsible and helpful.
