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

[LalaRu]

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

The tag match good with your FC name.

...an FC named Order of Bahamut was formed, and their tag was/still is <Aeons>. Why is this allowed?...

As long as the tag is completely unrelated to FC name, seems to me that they done that tag just to troll your FC


Edit: on secong tought, I recalled Bahamut is an Aeon, so that makes sense. But even if allowed, on create a new FC I think it is good practice make an unique tag. Maybe they were not even aware you exists.
