> On Earth, successful civilizations have been capable of trade and cultural exchange in addition to force.

Forget about what monstrosities we have done to other human civilizations throughout history. Instead, think about what we have done to animals. We have hunted many animals out of existence, or we have farmed them and made them basically the equivalent of the Matrix, sources of energy and food.

We are trying to eradicate mosquitoes for crying out loud, and entire species, without giving it a second thought. I will use insecticide to kill today entire colonies of ants without blinking.

All it takes is for one advanced alien civilisation to come across us and deem us the equivalent of their mosquitoes to eradicate us and take all the resources from the Earth. That's the whole point of the Dark Forest theory. If there's an infinite number of civilisations out there, and one of them is so advanced that we are insects to them, why wouldn't they just exterminate us, or use us as food?

We want to exterminate mosquitoes because they're actively detrimental. Nobody's advocating for the extermination of, say, daddy long-legs spiders even though they're everywhere; and nobody would be advocating for the extermination of mosquitoes if they were all located in Antarctica.

So it takes a very precise level of inferiority to be extermination fodder. If you're too unassuming, there's no reason and so it doesn't happen. If you're dangerous enough that you can fight back and hold your own, it doesn't happen either.

That aliens would find us just the right shade of annoying seems... implausible.

John Varley's Eight Worlds[0] series has an alien species called the Invaders. They invaded Earth to protect cetaceans from the effects of human civilization.

The Invaders divide sentient life into three tiers - species like themselves that evolve in gas giants, cetaceans, and vermin; we're in the third category.
