What constitutes GDKP?

I’ve never been a fan of GDKP’s. As far as I know GDKP means you bid on loot, and at the end that gold is distributed amongst the people in the raid.

I am wondering if in SOD would selling a mount I won for gold count as GDKP?
or NOT because there was no gold distributed at the end?

Yes because you are selling an item for gold.

doesnt like gdkp
wants to sell a mount for gold

My thoughts exactly kinds contradicting where is Elron when you him?
