Personally, I like this hack quite a bit:
I have a headshot aimbot, but it works TOO well and is very obvious when it's being used. I made my own AFK bot to work with it, I let it run for 2 full days, came back and have 1.5 KDR, but ...... 82% headshot ratio. Ouch...
My own suggestion would be slightly alter the Triggerbot to reduce recoil. It's a pain to use it with assault rifles or SMG's. Instead of holding left click as it's programmed, the altered one would rapidly tap left click, greatly reducing recoil and becoming more accurate. If that is at all possible (I'm sure it would take a bit to figure out, but sounds possible), it would be wonderful.
