In a recent post on the Rockstar Support fourms, they stated that the latest title update for Grand Theft Auto 5 includes improved anti-cheat measures and fixes for several game exploits involving the in-game cash, GTA$, as well as reputation points.
The exact wording on Title Update 1.09 was;
- Improved anti-cheat measures
- Fix for several GTA$ and RP exploits
While they did not give out any details on what exactly they did, we do know from their previous information that they do regular sweeps to find cheaters.
To keep the gameplay environment as fair as possible for legitimate players, we routinely do sweeps to separate out cheaters and modders, and to reverse any illegitimate transactions. These sweeps are based on in-game automated detection, examination of suspicious gameplay statistics, and also manually-reviewed evidence submitted by the Community. If you were not engaged in any willful cheating or exploiting yourself, you do not need to worry about getting caught up in our work to separate out cheaters from the rest of the population.
The update is available now
