@matigo ohhhh that's stupid! I had a F/E dev recommend that once and I laughed him out of the room. The second time he mentioned it I flat out said no.
Sadly, you might not have that option. Why not offload to Google Analytics and tell them they can have all kinds of tracking through that? Button clicks and all that. It's the easiest to block for the endusers.
It's amazing how badly data is handled in enterprise.
