I was awarded the "First Responder" hat late yesterday on Community Building.
As you can see the hat was awarded later than "Epiphany" (Jan 6th).
This is because there is a bug (or loophole) in the way the "First Responder" hat is awarded:
The room parent site - in this case for Ye Olde Hat Shoppe was changed yesterday by the room owner to communitybuilding.stackexchange.com as an experiment.
Everybody with a starred message in Ye Olde Hat Shoppe who also had a account on Community Building was then awarded the hat (on Jan 6th).
Note: The parent site has now been reverted to the default (no parent site).
It might be something to fix for Winter Bash 2017.
