+        We want to keep this server clean and therefore require that display names of all members on the server are
+        readable, accessible, and free of attention-seeking elements, which includes, but is not limited to, display
+        names that begin with hoisting characters, have an excessive number of emojis in them, or use "fancy fonts",
+        "glitch effects" and any other Unicode characters, which are either very inaccessible to screen readers or cause
+        annoyance to other members.
 
+        When we find that your display name does not adhere to this policy, we will try to correct it by changing your
+        nickname on the server. Repetitive attempts to revert to a violating display name may result in your removal
+        from the server. We will also permanently remove any users whose profiles contain inappropriate content.
