Alright, my immediate response to this, going from my observations here and on other sites (including one that takes high-level measures against harassers and general bad actors) is “Why are you trying to teach a pig to sing? It just wastes your time and annoys the pig.”
Clicking on a button to agree to a silly-sounding feel-good pledge isn’t going to deal with bad actors on OKC. Many people who send rotten messages don’t see themselves as any sort of bad person, and get confused when they’re countered in any way, or even get downright hostile if they’re confronted on a spiteful message, an attack, or anything inappropriate.
If you’re not willing to set out clear penalties for bad behaviour — a three strikes policy, perhaps, or suspensions of increasing length, or outright banning, then this pledge is toothless and pointless and nothing more than a theatrical exercise.
