Ok. This would not work. If you could do /report, the staff would have to go around the server to find out the person wasn't even hacking. Ive been accused of hacks many times (kill-aura, flying, anti-knockback and no slow) and if this was added it would be very annoying for players like me (and many others) who get called a hacker quite a lot. It would be annoying sine me (and many others who get called a hacker) don't hack. This would basically just waste time for us players and staff
