Ive received a link from my accountant in order to fill out my taxes. I added all my info, files etc. and today when I logged in, I had access to 4 other peoples tax returns. Address, bank info... all of it 🙂 

Interesting data privacy issue on our hands. Clicking on Contact us for help lead me here. So here I am. 

I also have someone else's avatar and an account number.
