Are you risking your GTA Online account by staying in lobbies with hackers?
The Problem
An increasingly common misconception among GTA Online players is that getting money dropped on you by hackers will result in your account being banned. The ban resulting from the sudden increase of cash you're carrying around. However, there are a number of ways to minimize any sort of harm that hackers may inflict upon you when and if this occurs. We've put together a hacker avoidance guide before, but that touched on different topics than this guide.
Dropped Money ≠ Ban
First of all, getting money dropped on you won't get you banned, and it has never caused false bans. Another misconception is that whether or not you bank the cash actually matters. Some claim banking it will save you from a ban, others that banking it is what causes the ban. Neither are true, because banking the cash makes no difference whatever which way. You're not getting banned for this, period.
Avoid Hackers and Switch Lobbies
One more thing before we proceed: the quickest, safest and overall best way to avoid issues caused by hackers is to simply hop to a different lobby. No method beats this right now. Even though a recent upgrade to the in-game anti-cheat allows for the mid-session banning of hackers, reporting someone won't insta-ban them since that system would be open to abuseby trolls and griefers, especially considering that absolutely every ban is non-negotiable.
However, if for whatever reason you decide to risk it all and stay in a lobby with a hacker, there are some precautions to take. Again, we'd just suggest switching sessions, but hey, some of you folk are off your axels. Sometimes you might meet someone who is a 'nice hacker', someone who doesn't crash the lobby with the spawning of infinite Titans, or doesn't take all your guns away from you.

Nice Hackers Don't Exist
First of all, there are no 'nice hackers'. They might not be screwy right now but you can bet that they cocked up other lobbies for kicks before, and will do so again. Any and all forms of hacking are in breach of GTA Online's EULA and ToS, and bans are issued in these cases.
Don't Enter the Vehicle
Now, while dropping cash on you won't result in the banhammer descending upon you, hackers can get you banned in other ways. A golden rule is never, ever to get into a car with a hacker. A number of hack effects, like god mode, are transferrable this way, meaning if you hop into a car with an invincible player, you'll be invincible too. But without any of the anti-ban precautions these hackers have set up you'll probably tick off the anti-cheat within seconds.
God mode isn't the only effect that is transferrable this way, but all of them will get you banned. The thing with hacking is that for all the masking techniques out there, none are fool-proof and even the best can only buy you time before you're banned. If any of you think it's a great idea to set up a mask of some sort and hop into a hacker's car as an easy way to get an unfair advantage, be warned that you're just signing the death sentence of your account.
