To all those asking about /f msg - we recommend you keep all 1-1 communication on services like Xbox Live so that Microsoft and it's content partners can properly handle situations related to abuse and harassment. This is for you and the person you're messaging's safety. We're trying to funnel user content through channels that keep people safe and secure, in accordance with laws such as COPPA in the US.
Unfortunately this is something that is out of our control. As a featured server we are partnered with Microsoft and so we must comply with certain laws and requirements to keep players safe. This is why there is no longer a way for you to private message someone on CubeCraft and why it will not be returned in the future. If you would like to directly message someone we recommend using Xbox Live's communication service, or if you must, a third party service such as Discord.
Here is an explanation from Austin, one of our Devs, that is pinned in our Discord server:
Ye thats right !I agree with the suggestion, but as Lyriee mentioned: They cannot bring it back since it's part of the terms of the server's partnership with Microsoft.
The problem is absolutely no one uses Xbox messages in 2025, and the word "Discord" is filtered by the game, not by CubeCraft, so it's difficult to ask someone if they have Discord
