Not to fuel the fire but...
I worked with one of our Long Island chapters in the late 1990s. There was an underground group which had been an NPC group that closed in the 70s and they were using the name of ABC (a NPC group). I contacted their HQ and they said they had heard the same thing and this group was using the SAME letters! They issued cease and desist letters to no avail. They decided to meet with the group and turns out they colonized there and took the group back into their sisterhood for a colony program. Turns out they did still have a copy of the ritual and it was a very watered down version. I moved away from Long Island in 2002 but a look at my NPC chapter and campus listing shows that group is no longer there. I suspect they were never chartered and ABC retrieved what they needed from the group for good.
Can I have a cookie just for sharing?
