Let me explain how stupid you guys are, in a new way. Getting hacked sucks, and it's all technical and stuff, but there's a really dumber way to get "hacked." Doesn't take any smarts at all. All you have to do is assume some trash has value, and then lend against that trash. The $AAVE system did that. So instead of needing to get "hacked" to lose hundreds of millions of dollars, they just had to support a lending market for the trash.
So now everyone that had WETH (wrapped Ethereum) on AAVE is screwed, because the hackers emptied out hundreds of millions of $ of real WETh in exchange for their trash, hacked tokens that AAVE supported for lending.
TLDR; you don't have to get hacked by smart folks to lose hundreds of millions of $, you just need to support lending on trash.
Idiots all.
