Has anyone heard of Gamestop's new game trade policy?

I read a story online about a person who went to Gamestop to trade in some older games for new ones and he was asked for his ID and social security card. The guy said that he didn’t have his social security card and they wouldn’t accept his military ID.

He said that he refused and came back later when other employees were working and was asked the same from them, so he doubts that it was just a local scam.

Anyone encountered this? What do you think about it?
