Looking through the logs, this is what I see:
- Lau not following directions, getting killed a lot, but still contributing to the fight (ie he wasn't intentionally dying, he was still getting kills)
- I did not see any evidence of attacking siege shields in the logs, but other admins were there who could possibly confirm
- It looks like there were concerns with the attackers delaying at the end of the battle by not actively fighting, which muddies the water.
To me, it looks like what Lau did was opposed to what his teammates were telling him, but there is nothing directly against the rules with what he was doing since he was being reckless but not full-on feeding tickets/intentionally griefing. Would I myself hire Lau? Probably not, considering what I read in logs. However I think this is more of a "I'm not hiring him again" situation versus a "he should be banned for griefing" situation.
I'm going to lock this for now without banning Lau further, but will check in with other admins who were there if they saw things I cannot from the logs.
