Enable a wild card for blocking multiple spams from the same source
It would be so helpful if there was a wild card character we could use when blocking multiple user names from the same place. Apparently there is something out there called "firebaseapp.com" that is generating a large presence, but each email gets a few characters in front of "fire" to represent a different user.
IS there something that can act as a wild card in this type of situation?
