With the recent number of admins present on the DB servers it would take at least a week of ruined gameplay before they received their 4-12 hour ban, which wouldn't do much to discourage their behaviour.

Even though GoldenLunchBox is the one reporting me, I think he would make a great addition to your staff, and you should look to getting his application approved asap.
Your main issue with his application was activity, but every time I've played with him (also in the past) he's been a voice of reason and behaving very mature, which in my opinion makes up a great deal for his break from the game.
Besides, who doesn't take a break from a game every now and then?
