Hello. I have already my own external triggerbot. Trigger is using memory reading. It's undetected since May, 2014.
For sure trigger will work on VAC/Faceit and serverside anty-cheats.
If you choose my offer i send you:
-Memory class
-Offsets pack and programm(not made by me) to easy update offsets
-Full external triggerbot source code
Trigger has options to:
Set shoot delay
Auto Shoot / When button is pressed
Fake shoots (When you kill enemy trigger will shoot some bullets more)
Im only 1 user and owner of this source and trigger.
