Unless your sticks have been made/set to digital, we definitely can tell. M/KB players' characters start off sprinting and come to full stop when moving and stopping. Whereas controller players accelerate into a walk then run and likewise slow down when coming to a stop.

The only PC players on a Keyboard you'll see walking are RPers.

As for preferences, people may group with whomever they wish. What I don't understand is why the OP is ticked he can't group with these people. Why would he want to group with people that do not wish to group with him? You're not missing anything except for arguments.
