Basically i got bored and had this idea. it works by every 5 minecraft days, if you dont use the /payirs command with EXACTLY 5 diamonds in your inventory, no more, no less then the IRS spawns and raids you. remember to pay your taxes!
admins can also use the /setdiamondtax followed by a number to change how much you owe the IRS.
this was a very silly billy idea by me so please use it on servers and have fun, if it breaks with multiplayer please let me know, maybe if i can be bothered i will add a command to change the interval days as 5 days (100m) isnt that good for starting.
who knows maybe if this project gains traction i might even turn it into a mod aswell.
thanks
