I honestly don't see that as ban worthy, maybe warning worthy, but not much else. Might have just been a bad day for him when you caught his eyes. Personally myself I've only been banned once and it was for 1 day. Though I still refuse to accept the ban since it was based on false logic that had no proper backing. Argued my case, but was pretty much told "I don't care".

Its all behind me now so meh.
