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.
As a mature person we must not teach our children in pornography using bitcoin but rather we teach them that bitcoin is a good business to invest with and we can rely our future with the success of this technology.
