If anyone remembers the Ike situation, that was similar to this, but the difference was he admitted it while he was on the server, and was using them at the time of playing. Therefore there was proof of him using hacks on the server. This, on the other hand, lacks context, and while we all know Cyber is an upstanding member of the community and has never shown any indications of abuse, it's unfortunately not good enough.
We don't care if players hack in other games or other servers, we care about what they do here. We also require demos of them hacking in our server, and while a demo of them hacking somewhere else is great added evidence, it's not enough to warrant a permanent ban on it's own.
A steam chat is also not enough to go off of as there are too many unknown variables. Could I not change my steam name to "thecat|ibis.a" open a chat with another admin and admit to hacking and beastiality? Now I know Cyber wouldn't do something like this, but what happens when someone with less credibility makes a similar post? One where we may not know the intentions of the individual as well as we do here. As was said before, I believe this sets a bad president and as Cyber referenced previous cases, so could this be referenced next time.
Cyber, is there any way to get the demo of the actions in question? because then it would save a lot of muddy water in the process.
