I most likely overreacted with this change.
So that whole "Balding Miku" edit might have made me become a little too strict when it comes to restrictions. Instead of having only registered users being allowed to edit the character pages, I changed the restriction to only administrators and content moderators.
As for the person who made the edit, they made a comment linking to various Twitter posts about "Balding Miku." I responded simply by saying that type of information is not necessarily what the page needs, and that "Balding Miku" is more of an opinion, artists have different art styles and draw hair differently, etc.
If this causes any issues please notify me. This change will most likely be temporary as this Wiki is small.
