Here’s the answer to at least one “hitman” service provider on the Dark Web. BesaMafia offer contract kills and other forms of intimidation for a price. Today it was announced they were closed for business with an explanation on their now-defunct hidden service:
“Besa Mafia has closed for business. After 6 months of scamming criminals for their bitcoins and stealing over 100 BTC ($65,000), the site has closed. No one was ever beaten up or killed.”
Well now we know.
