This is a very simple idea but I would think that it would be a very nice idea for when staff members are afk in-game and when a person msg's them looking for help that like a bot would automatically respond to you saying that that staff member is afk and is unable to respond at the current time and might like refer you to somewhere else to look/ask for help. I think it would be a really good small addition for people who are wondering why staff members are not responding to them when they are afk and the person asking for help doesn't know it.
There used to be something like that in the past but im not sure why its not a thing anymore. Support
It isn't a thing anymore because we don't use the essentials plugin for messages anymore. The plugin used is the friends plugin which needs to be coded. This suggestion also has been made before and Matt said that he would attempt to add the feature. Though it is uncertain when he can. Skyblock Official Site | Skyblock
You can also /seen (staffmember) If they have used the /afk command before going AFK it will say AFK:True in green (&a) It’s just a way to check
