Firstly a VPN does not protect you from hacking or DDOS attacks at all and it only provides "semi" privacy depending on the VPN service you use and your habits while using a VPN, most people are not hard to trace through a VPN as they expose themselves in so many different ways from browsing habits, to social media access etc etc and really it is just no one needed to or wanted to trace you.
personally I use a VPN for when I really want to be anonymous, for that I have a specially configured VM.
