|This essay contains the advice or opinions of one or more Wikipedia contributors. Essays are not Wikipedia policies or guidelines. Some essays represent widespread norms; others only represent minority viewpoints.|
It's good that people volunteer to work on Wikipedia. We're grateful for their hard work. But with that work comes responsibility. We ask that contributors check their facts and take some pride in their work. We ask that they collaborate with others. We ask that they behave civilly and with respect. Asking that they use an appropriate username is an extension of that, and not wildly unreasonable.
