Use common sense is a fundamental philosophy on Brickipedia. Following this rule is very simple; all that you need to do is use your common sense. If something seems like a stupid thing to do, don't do it. If you are worried that your actions will offend another user, they most likely will.
Additionally, if a rule prevents you from improving or maintaining Brickipedia, ignore it. Common sense overrides all policies and guidelines; you can break all the rules you want as long as you have a reasonable explanation for your actions.
