Can we change this users name? This looks silly
If their username contained profanity or explicit content (yes, this has happened before with other users) then indeed it should be flagged. But the name of a viral disease?
Should we ban "flu" then?
Even if the name were something silly, like Bob The Builder, we would still have no right as mods to go and change it or even to ask the person to the change it. So long as it is nothing offensive or profane, we really have no reason to bother anyone over a name.
