JUDGMENT

Well, here we go...
What does personal acquaintance have to do with it? Now the mudslinging, flaming, etc. will begin.

You just want to see it happen... that's why it seems to you that it has already started...
Don't worry... nothing will happen... I think everything is already decided here... and not by me or you...

Regarding what prevented him - it's the same thing that made him confess, effectively signing up for a ban...

The act was deliberate and calculated... he should have thought about it earlier...
It's too late to cry over spilled milk (idiom)...

You write as if all people are your enemies, as if everyone is cheating and plotting... that's too much.
And OPTIMAL has already written TWICE that this case is unique!

Here's a question: how can you judge a person based solely on a message about his cheating that you saw on the forum?
I'm not saying I know him well, but I at least played with him....

This is also too much... What makes you think that this case is unique??? It's not up to you or Optimal to decide... it's up to the Forum Administration!...
The answer to your question is nonsense. You didn't communicate with him, you just played. And you played with the monitor, not with him, and there probably weren't any "life" conversations during the game.
