How to make an auto in-game kick for users who have been in my group for less than a certain amount of time?

I am trying to make a veterans rank for my group. I want to make it for people who have been in my group for a while. I am making a game that will auto-rank you if it knows you are a long time group member. Anyone know how I might be able to acquire a script that will automatically kick recent members of my group?

Roblox provides no actual method of achieving this the only way you could achieve this is by doing a hacky method: Method to checking how long a player has been in a group?.
