Is there another way to look up player name history now since RTB is gone?

I don't think so, RTB recorded the ID's name for every server it joined and archived that name into a list when it was changed. I doubt there is one unless Badspot has something for himself.

ID mapping project:

The catch is that not all the past names of players are shown. A player's name is only recorded when they join a HammerHost server.
