Do the Catholics still do that?
Yes, they still do. And did during WW II. My father was excommunicated for being a member of the communist party.
As for collaborators being excommunicated; not many.. I know that members of the Dutch pro-Nazi party were, and John Paul II excommunicated Williamson, Lefebre and the others of the Pius XII fraternity, an ultra orthodox lot that wants the Tridentine rite back and generally thinks that jews are the cause of all evil. But Ratzinger took them back in again in 2009.
