FC Has Same Tag As Mine on a Technicality. Why is this allowed?!

[Kuroyasha]

So in October I created an FC called Dark Aeons with the tag <AEONS>.

As I understand it, an fc cannot choose a name or tag if that name is already in use, as I tried before way back to test it. In February, an FC named Order of Bahamut was formed, and their tag was/still is <Aeons>. Why is this allowed? Clearly if we're not allowed to use same tags we shouldn't be allowed to use it just because some letters are capitalized versus uncapitalized right?

Is there any way some GM can take care of this? Or maybe devs can patch this so you cant have the same sequence of letters regardless of capitalization? I'm being swagger-jacked

Edit: Some of my previous assumptions were corrected. Original question still stands; Why is this allowed? Pretty easy way to cause confusion imo.
