Every single lobby that I have seen on here since yesterday have been either completely fake, or super high demand. Even the ones that are high demand probably aren't legit money/RP lobbies because I have yet to see any sort of proof of people getting money from them. Face it, there aren't any lobbies out there right now and you'll just have to wait until somebody finds out another way to get money into the game.
All Rockstar cares about is making money, not player experience, so expect them to roll out harsher penalties next time and expect them to devote all of their time patching exploits instead of releasing the rest of the features like heists to GTA online.
