Are you talking about posts on the rent trade board here? If so, it might be that someone had a reservation booked in the Disney collection exchange options, and had to cancel, leaving those points as "reservation points" that can only be used for other "Disney collection" exchanges.
There was a lady on the point rent/trade board that has 200+ points that can only be used at several of the Resorts (Contemporary, CS, POR, etc), at Disneyland and something else. They cannot be used at a DVC. I had never heard of points for resorts and wanted to see how that worked.
As Diane mentioned above, if you make a reservation for a Disney hotel using DVC points, and then cancel that reservation, the returned points become 'Reservation Points', and can only be used for non-DVC reservations at that point.
