Modding used to be extremely easy and detection systems weren’t implemented yet back in the day. I have an account with billions in cash just for being in the same lobby as one.
These days you’re still free to ruin everyone’s day with all sorts of griefing mods, but once you try and spawn in cash daddy rockstar gets angry at you.
Also fire departments, hospitals and other medical services. They’re extremely reliable, last a very long time on a charge and don’t shatter when you accidentally drop it.
