I would Highly recommend a RDP /VDS
Remote Desktop Protocol // Virtual Desktop Server.
VPN's wont keep you safe, if you crack on your main build make sure you use Sandboxie, Good Proxies, and Hide My A** (HMA VPN) or Private Internet Access (PIA VPN)
Use a VPN, then connect to a RDP / VDS. Do not keep any cracking software / information / combos/configs/anything related on your main build. Keep it all on the RDP. Upload things to Throwbin if you are leaking or anonfile if you want the file to be private.
Then post on your build. Dont login to Nulled on RDP / VDS. Run google chrome through sandboxie (on rdp) and copy download links and tools( on main build which is logged into nulled.) and download them on sandboxed chrome on RDP.
