Hi Brogan, member is registered from 2015.Were the requests received before they verified their accounts?
What is the change username permission set to in the unregistered / unconfirmed user group?


I ran a few tests on a vanilla XF 2.2.1 install (no addons) and found that... a regular user could not request a name change with the user permissions settings as "No" for the main "Registered" user group.But, I've also another username change request, and from the changelog it seems that he didn't changed the email..
That is most likely.Maybe that he went in the unconfirmed status when he changed the email address, and used this moment to change the nickname?
There may be a delay before changes are rolled out to the XenForo Community.Ensure only valid users are able to change their username.
