I'm sure it is a one piece derailluer hanger with no dropout. Looks like that would be a good idea! There is some kind of thread material that is not aluminum that came out with the deraillure mounting bolt.
I agree that this sounds like a rather gratuitous insult to those trying to provide the info you requested. Your manners need work.
If the threads that came out with the derailleur were steel, not aluminum, it's possible the derailleur hanger was repaired in the past with something like this:

Dealers commonly use them to repair damaged rd mounting holes or it might even be an OEM part to strengthen an inherently weak threaded hole.
