Excuses one catastrophic reply-all incident, provided nobody important saw it.
Hell invented the Waiver after watching Simon Pratt from Seattle reply "Thanks" to 184 people, then immediately send a second reply-all saying "Sorry everyone". That second email is still used in training. Satan keeps a framed copy near the lifts because it proves something he has always believed: humans do not need temptation, just a visible button and a moment of confidence.
