Hayz, another black shit staining propaganda. Why even bother?, some people with ill intention will create a reason to hedge the progress of bitcoins. almost all of these cases are already deep rooted in the internet, and since we live in internet, why bother?. These kind of services won't stop any time soon because everyone has free access and can stored their ill gotten data on bockchain. So don't fret it's nothing new.
It's doesn't affected to me pornography using bitcoin that's the attitude of individuals we cannot stop them that thier own expenses and that's thier coins what ever they wanted to must be responsible for it.
