GM is now very funny, people who buy lists or sellers can be banned permanently even though they do not know that it is a duplicate item that is sold to people who buy the list.
Those who buy the list are not guilty, not all of them know that the goods sold are duplicate items.
There may be more and more people who are the subject of GM's allegations of "being concerned with duplicate people"
How long has GM accused the person who purchased the list always concerned with the person making the duplicate?
