I disagree. The JJ of JJ Aldrich is all that she is known by. Look at Sherdog stats or Tapology. Do you find any mention of a first name or middle name? There is none listed. Nor is there any fighter nickname. She is simply, and officially, JJ.
Joanna Jedrzejczyk, on the other hand is not officially "JJ". That is just a convenience that lazy Sherdoggers use that don't want to type "Joanna". That was fine until you have a TUF series with an official "JJ" in it.
Now it is time for Sherdoggers to adapt to the new situation.
