Help anti kill farm skript

[zAngryy]

Suggested name: Anti kill farming skript

Spigot/Skript Version: 1.12.2/latest version

What I want:
I need that a player cant kill another player over a max of 10 times in a range of 30 minutes, for my kitpvp server

Ideas for commands:
I was thinking to set {killed::%attacker%::%victim%} to a start value and to reset it every 10 minutes
Then the skript has to check if {killed::%attacker%::*} is of a size more than 10 and execute the command: "eco take %attacker% 1000"

Ideas for permissions:Nop

When I'd like it by: As soon as possible, maybe tomorrow?? REALLY NEED IT all guys are kill farming in my server

I think your idea with the variable is the only solution(I can't imagine anything else). So you already wrote down the solution you need, why didn't you use it and instead decided to wait?
