How do I add to a config list from a command?

Hello, I am currently trying to make a punishment plugin and one of the feature I want to add is to be able to check a players punishment history. I am trying to do this by whenever someone bans/kicks/mutes/warns a player it adds it to a list in the config. Here's an example of the config.yml about what I mean

Code:

#Config

{Player UUID}:
   history:
      - {bans/kicks/mutes/warnings here}
      - Examples:
      - Warned by ObviousEmeralds for spamming
      - Muted by ObviousEmeralds for spamming
      - Banned by ObviousEmeralds for Fly hacking

If that won't work out, is there any easier ways to do it?

 

@ObviousEmeralds
Store all the violations as an arraylist, and save them using the following line.
getConfig().set(UUID+".history", Arraylist of all the violations);

 

The ban command would be /ban <player> <reason>... Not /ban <Player> <Violation>

 

@ObviousEmeralds
But still, that is how you would store all the violations for a player.

 

What if someone were to do "/ban <player> Flight Hacking - Moving smoothly through the air"

 

You can check if the second arg is a player, if it is, then add that to an arraylist. then cycle through the rest of the args with a for loop, adding it to the arraylist. then cycle through the arraylist to form the reason why the player got kicked/banned/muted/etc. then add it the the config by Zombie_Striker's method. That's how I would go about it; not sure if there is any other way too
