Wikipedia:Because I can

An almost sure sign of a problem editor is someone who has "because I can" syndrome. You see this play out like this: Editor A notices something he thinks is a problem. He says "Hey, Editor B, please don't do this." Then editor B quotes some rule and insists that he's allowed to do it. Editor A explains why said behavior is harmful. Editor B merely blows off the objection, and insists he'll continue doing it because he can.

Editor B has a temperament that is fundamentally incompatible with a collaborative project like Wikipedia. Since Wikipedia isn't going to change to match that misguided temperament, the editors suffering from "because I can" need to either change their ways, or refrain from participating here.
