i just figured out about tapping yesterday and some1 said they are sending a message to nexon with proof of me saying "if dcing the ethernet cable is a hack then nexon needs to get some fucking brains"
Dude I did that once in a 16 player Spy Hunt in Waverider.
I killed all the people near me when I got SS then I went in the building on Bravo side and hid in the corner and started tapping, went in the lighthouse and killed about 5-6 and about 4 along the way there, then I checked the rooftops and in the 2 buildings by machine.
After that I pressed my tapping button and waited about 5 seconds nervously waiting, and then there it was, Unbelievable+! I killed everyone but about 6 people. Checked CBL a day later and still CBL clean.
