It's not that easy. The site will also have to deny to remove the contents. I'm pretty sure SO would remove such content, simply because it's off-topic there.
I'm sure there is sub-exchange on stackexchange, where it's not an off-topic. And as soon as stackexchange share the IP with SO it will be blocked all over. Thanks for the idea.
Then, there's still the question whether SO will comply or not. Given that reports of suicide trigger more suicides than without, I wouldn't be surprised of SO community guidelines which discourage such content, even though it might otherwise be ontopic in that specific sub-exchange.
