That has nothing to do with coding, sinking islands or any other thing we could do. Sinking an island just to "renew" is is a lot like nuking planet earth into a wasteland in order to get the corrupt politicians who have taken over out of power. It's... not strictly wrong, and it'll accomplish the goal, but it is a tiny bit excessive and it will damage the innocent most and those you want to hit least.
You do realize the irony here, right? The exact same metaphor applies to suddenly and arbitrarily shutting down the Local board on the forum just because a few people happen to be dicks. Meanwhile, the majority who generally abide by the rules and enjoy the Local board end up getting hurt.
