I keep thinking this can't continue to be a worse PR Nightmare for Bethesda and every day I'm surprised at just how wrong I am. This really seems like a slam dunk for a lawsuit. Apparently the said poster at one point posted a screen grab of said leak confirming this but it looks like the picture has since been deleted.
In short this was posted on the /r/FO76 reddit:
Hi guys! First time Reddit poster here. I am a gleeful vault dweller as yourselves and as of this moment I am receiving every single one of your support tickets on my Bethesda account. Mostly it's your receipts for you power armor set requesting a new bag. These receipts contain all your info. Your email and home address and the card you used to buy this extremely glitched game. I can see the problems you are having with the game, yes I'm having them too. And I know a few of you want a refund that Bethesda has said can't happen. I can update your ticket for you, if you'd like. And close it! How fun is that? Please rest assure I have no desire to stalk you or mess with your Fallout 76 experience. I just wanted to let y'all know that this is happening atm. Anyway, I gave Bethesda a heads up via the Twitter. So we will see. I wouldn't want to be the person having to respond to all of you. Currently there's 8 pages of canvas bag requests, tickets and "fix or refund me" demands. Is there anyone enjoying the game like me? Oh well! See you in Appalachia. Be nice to each other. I love you!
