That's seems more like a browser issue, but none the less, any links on Hacker News could do the same.
I don't consider that malware to have to close an application, just like I don't consider a malware a link that rick roll me (which still force me to close a tab ;) unless I want to stay on Youtube).

Aren't we talking about running malicious JS? Any link you click can contains malicious JS, yet you click on that link without thinking about it, but when it's an ad that may contains malicious JS, you block it altogether.
I don't understands really what you means by not what happens.
> Maybe you should contemplate the possibility that you're wrong.
I contemplate each time I'm discussing with someone about it. I still haven't got any evidence about it.
Each time I ask someone that does it for "security purpose", when they don't answer by "do your own research" (which I always try when they say that even if it's absurd to have nothing to defends yourself), the best example they always have is either link to some report with stats that doesn't define malware, or the Forbes case of when one of their ad was a fake Java update. If that's malware, then here we go, HN now serve malware too: Click on that URL to update Java: https://forbes.com
If we were arguing blocking Javascript for security purpose, now that does make sense (still pretty unlikely, but based on news, it seems to happen much more).
