Just like how prop hunt works in Team Fortress 2.
People being able to look around, but being seen as frozen in place.

I'm trying to achieve this in CSS for developing a plugin for a unique spectating mode.
All it needs to do is prevent the player's model from rotating (looking around).

To prevent them from rotating, you may have to constantly set their view angles :/

I don't think there is a move type to prevent rotation. Mabye some netprop to reduce rotation speed?
