Here is a more in-depth thread on the FC:ND steam forum:

The game let's us post screenshots etc but it doesn't show up on our Steam profiles at all, only in our library.
On my "recent played games" section on my own account FC: New Dawn is nowhere to be seen and it seems like it's the same for most people.
