The use of Mode C is also for your benefit. Although the "C" may be unverified the likelihood is that is it a reasonable indication of your altitude. We see traffic not working us with "C" on we pass the traffic and say "indicating ****ft unverified" the other aircraft is able to look above or below it to find said aircraft also they sometimes decide to climb or descend to help with their separation.
As an aside but with reference to Andy's post when we verify Mode C if the figure indicated on our radar screen is with 200ft of that stated by the pilot we consider the "C" to be verified
I have said it before and will say it again , we are not there to Police the skys we are there to help pilots out, so why do they think we are in some way Big Brother
