Yeah dangit Forum rules are objective not that they came from "objective thoughts", but they are made objective. For example: The information is clear, and the reason behind the rule is also clear: to utilize the tag feature correctly. If someone tags their posts incorrectly, they are acting against this rule. The reason behind this one: to confine the scope of discussions to PocketMine (or Minecraft: PE servers) only. If someone makes an irrelevant post such as discussing which is better, PC or Mac, they are acting against this rule. Now what if... Okay, what is the reason behind this one? If according to your previous posts, the reason is "moral values". Because the behavior acts against "moral values", therefore the behavior is not allowed. Great, which means there is another hidden, unspoken rule behind this rule. Alright. The reason of the rule could be, PocketMine as an international forum, shall actively promote the good side. But how would one judge for this rule? Everyone, including every moderator/administrator here has their own moral values. Your moral values may disallow someone from trading, but someone's else may become different. Here comes the subjective part, and unless you objectively define "moral values" in the context, this rule is certainly not suitable as a forum rule. Of course we are talking here all being subjective for our own's opinions. But I can say unashamedly, that I have listed several objective arguments to support my subjective opinion. From similar examples, to the application of GNU license. But moral values - that is kinda moral blackmail to me.
