Peek-A-Boo
A very respectable Modder named "Chr0m3 x MoDz" figured out some interesting things. How R* detects things & what not. I will just post what he says...
Ok so after doing a bit of reversing and looking through things trying to bypass cheaters pool I have found some intresting things.
So the first thing is there is a function that checks whether to define you as a high earner
When the game defines you as a "High Earner" you will be flagged and then rockstar will investigate your earnings.
Being sent big $$ shouldn't get you flagged but receiving big $$ and RP on missions and what not will deffinatly.
Now here is some more checks.
The game will monitor your kills and if you get picked up as a possible cheater / booster then again you will be flagged and investigated.
They DO NOT monitor your bank or cash at all. they DO monitor your cash earned! (Thus the reason why with my service no one has been cheater pooled / banned)
With my services the cash doesn't show as earned its just set straight in memory.
And here is where they reset everything when you get put in cheaters pool.
If posted elsewhere please credit me.
Alot of the tunables multipliers also have var checks for min and max before you get flagged.
