I don't want to try this, so use at your own risk if you intend to do it.
Status: Untested.
1. Create a new account, launch project blackout & login.
2. Open a packet editor program (must undetected by hshield), in picture below uses rPE Packet Editor.
3. Click the button to capture packets.
4. Back to game, you will see your EXP is zero so let's increase it.
5. Click Mission/Title icon (at bottom), you will get +100 EXP
6. Go back again to packet editor, stop the capturing.
7. List of captured packets will show in the list, find the ones that look different than others or look for out/send packets.
8. Send back those packets continuously, set timer to -1 or -10, & don't forget the socket id then click ok.
9. In game you will see your exp keep increasing like mad but you will get a connection error, just ignore it.
