Thanks a lot for this analysis.
Being untraceable on the steem blockchain does not mean necessarily not using it at each instant and for each transactions ;)
We made a choose between giving fun to real players, or to few people who are using bots or the blockchain itself to track others. It may be not important depending of the game, but for DW it is a must have to make the game more fair for everyone.

We also offer social logins with facebook, google and vk. and those numbers are not taken into count in your graphics, but whatever we are proud to give life to the gaming on Steem beside SM and NC.

Again thanks for your time.
