That's fair, but I don't agree.

For me, you can only betray the trust of people who are in a trust agreement with you, like friends. For me, you are not implicitly friends with other CF players.
You do however, explicitly agree not to cheat.

Additionally, even if you were, it wouldn't make sense to me for the Staff, the only party that can enforce rules, to hierarchically subordinate rule enforcement
to this friendship-lite arrangement, because consider, with regard to basic decency and trust: don't players also have an agreement with each other not to cheat?

If you've potentially cheated and if the person sending in the 'proof' definitely cheated and is admitting it, why is your privacy with your implicit CF friends (TM)
a higher decency concern than that of the rest of the players right to not have to play with cheaters who are breaking their trust? It's such a big deal that they
should even just ignore the guy who is ADMITTING he is cheating in the chatlog?

Do you see why this isn't a black and white moral issue?
