Don't worry the guys were very thorough and never game someones name to Relic unless they had multiple very suspicious games or one extremely obvious game like strafing cloaked stormtroops (yes people actually did that Kappa).
Unfortunately this thorough approach was both a blessing and a curse in CoH1. People would only be banned for maphacking if there were like a million replays of them cheating. This meant it got really timeconsuming to hunt down cheaters, and a lot of cheaters would get away with it cause they only got reported once (which should still get them banned if it's clear in that specific replay they cheated!).
I do understand that sites like gr.org and coh2.org don't do naming and shaming. But not doing that, actively banning discussions about cheating (thank god this thread is still open), and only banning cheaters in case of overwhelming evidence simply results in cheaters not being battled effectively. Unfortunately we have all seen the results of that in CoH1.
Edit: Only "not-so-smart" people will actually get banned for maphack with the requirement of overwhelming evidence. It is just too easy to maphack, and not show that you do. Just don't kill snipers you can't see, don't destroy mines you haven't detected and DO use the info you get from where all his units are (and again; dont make it too obvious). This way pretty much any cheater with a brain can get away with cheating without being banned ever.
