This sounds very annoying to do every single round for every single person manually.
It's insanely annoying of a concept, and leads to problems where because of how it would work mechanically in a text based game, if 3 people were talking at once you wouldn't know who said what. Even worse with radio comms
I don't need to know people to be able to at least follow a conversation.
There really is no way to mechanically enforce this sort of thing that doesn't either break communication as a concept, or just result in some silly system where you have to be super mindful not to accidentally metagame (Such as giving each player an "alias" at round start for radio you ahve to discover).
The other thing, face recognition, arguably makes even less sense. You work at a place long enough, you recognize people quite easily. I can still remember the faces of around 100 people who shopped at the store I cashiered for, and the interaction with them was nothing more than "Your total is $63.21. Your change is $2.79. Have a nice day". One could argue you wouldn't know their name just their basic description, to which I'd reply that we are playing a 2d spaceman game where physical description (not counting examine, which can be hard if they are moving) is 10 blurry pixels and if you're lucky a hat.
The concept just stinks of mechanics for mechanics sake.
The only thing that needs to be said is instead that people need to perhaps be less good at recognizing others in a crisis situation, like when attacked. But that's something that can be solved with some gentle nudging and RP standards, not upending the entire game experience with overly labyrinth mechanics that ignore the limitations of the medium. And that's already something that takes car of itself already, with things like "Who attacked you" "I think it was the chef?".
However, if I was to play devil's advocate and suggest a mechanic that would help in these regards, perhaps culling the message log would be a good step? So you don't have a perfect log of what everyone said the entire 2 hour round. Maybe after say 5 minutes or so messages drop off, so if you can;t remember who it was, well, you can't remember.
