Sadly, over the years, the powers that be have been led down a seductive path. In the fear that they may get a decision “wrong,” they have resorted to trying to establish bright lines to measure jerkiness by. This way, they think they can accomplish two purposes: warn away potential jerks by giving them concrete boundaries not to cross, and make decisions about whether or not someone is being a jerk without having to worry about being wrong, since they can point to a rule and say that the rule is being broken.
This process was accellerated at the time we went to Pay-to-Post, because the assumption was that the paying members deserved some sort of spelled-out boundaries, part of the contract, as it were. Else, presumably, those upset with a decision based upon something as nebulous as “you are being a jerk” could complain that their purchased right to participate was being violated.
The assumption that creating a slew of rules will help manage the game is false. Soccer understands this (or it used to, anyway), which is why it has only 17 “laws” that govern the game, and most of them are pretty simply stated. Compare the rule books for sports like football, baseball, etc. Or, if you prefer, ask yourself if modern Dungeons and Dragons is more enjoyable for participants and DMs simply because every possible situation has already been thought out and a rule for it created?
This place would be far better off if it returned to a less rule-bound organization (and I say that, having been an attorney!). As a teacher, I find it much easier to limit my “rules” to a few generalizations (respect your teacher, for example), rather than trying to add a rule or an addendum each time someone manages to screw up. Yes, this can result in accusations of unfairness and favoritism, but I’m confident I can avoid that on my part if I do my job right, and frankly, they end up happening even if I apply a list of rules an arm long.
Tamerlane has it pretty much right, sadly. It’s up to management to simply stand its ground and say, “you were being a jerk, in our opinion, so we are suspending you, and comparisons to other situations aren’t relevant.”
