Griefing in Fallout 76 is pretty much non-existent - it's an overblown "headline".
That community has been one of the most friendly and welcoming communities of pretty much any multi-player game in the last few years. Asking a question or for help from a complete stranger and getting way more information or assistance is actually the more common occurrence.
The game has been around for a long time, so welcoming or helping a newbie is sometimes a nice break from the grind for the high-level players.
Come on over newbies - the game has changed a LOT from its original iteration (which WAS a shitshow full of bugs and griefing - which is outdated information from long past).
