This is a sticky at the top of this forum:

It does clearly state that if you're seeking help about someone who has the disorder, to kindly use the Relationship or Caregivers forum for it.

And yes, I see that Matt posted the link too, but I'm still linking it anyway as my response is based on that thread.

The fact is, even though the OP isn't being derogatory... it's about someone else, and someone who isn't diagnosed with NPD. By posting and listing off all of the horrible things that this person has done... it's indirectly going "This person is horrible=they must be NPD=NPD people are all horrible". The forum is for people who are diagnosed with NPD or have at least self-diagnosed themselves with it - and are seeking support for themselves. Whether that support in their threads comes from other people who have NPD or others who do not have NPD is fine.

But the OP in this thread does not have NPD, and does not suspect that they have NPD. They suspect that their mother does. When the thread is about someone else, it belongs in Caregivers or Relationships. Sometimes Survivors of Abuse.
