I was walking down the street and a guy was waving a sword around with his eyes closed. Before I could react, he thrust the sword deep into my chest. Through some miracle, he avoided every vital organ and, stuck to the end of the sword as it burst through the back of my ribcage, was a huge cancerous tumor. That guy saved my life!

^^^^ this COULD MAYBE happen. I still don't want people to stab me with a sword.

I could MAYBE get spam that has something I want to buy. I still don't want to get spam.

When someone fav's one of my tweets, I get a notification. I like this because it tells me that someone liked something I said. It makes me happy. This reduces the value of these notifications and, if it becomes widespread, will probably make me turn off notifications, which will make me sad. Don't you see how this is producing negative value?
