Ability to change and island Is Value from within config

[ZxcyyZ]

Description

Is your feature request related to a problem?

Due to our server having that competitive aspect to it, we'd like to have rules where if a player was caught using a macro then there island will have there island value reduced by 10%, this is so your actions have consequences for others rather than just yourself.

Describe the solution you'd like us to implement.

The solution would be maybe within config somewhere, within maybe a players island file you then have the ability to change the island value within that island file. It would then remove X number of blocks associated to this worth (this could be spawners/any blocks set).

Describe alternatives you've considered.

I hardly see how it could be done through config, however maybe as some sort of "modifier" that we can apply on the island level with a command?
