Normally we don't disclose findings of reported cheaters to the public other than to the reporter- IF we find the report to be valid... but after reviewing the submitted reports on this person I couldn't find conclusive evidence of cheating.
If you feel TF2C is failing to deal with this person's alleged cheating then I highly recommend you submit the same evidence you've given us to various league anti-cheat admins. They can review it and determine if the person is cheating or not. As they do ban players for cheating outside of league games:
If any league bans the player for cheating then we will follow suit.
