I understand what you are saying, and it sounds reasonable, but I disagree. Your basically suggesting that in every case of a banning, they need to publicly shine the light on every infraction. They also need to spell out an exhaustive list of "strikes," and beware if they forget to include CAPS-YELLING in the list.
No. This is an adult we are referring to here. We can reasonably expect that he knew exactly what he was doing, and was merely pushing the line as far as he could go, and just happened to cross it. This wasn't the first time; he was a repeated offender. This wasn't the start of the problem. It was the final straw (which, in my experience, is usually a minor straw when compared to the haystack beneath it).
Edit: Thank you for responding with a more clear comment than you original, btw. =)
