This post asks to disallow usernames with only periods and spaces. I would like to propose disallowing any឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵឵ username with more than one consecutive space. Furthermore, usernames that have more whitespace/blank characters than non-blank characters should also be disallowed. Such usernames make it extremely hard to click on user profiles and ping them in comments for little benefit. To demonstrate this, I have changed my own username to U+17B5 (឵).
