If you are not okay with not filtering for the ranks you are currently at despite sending games at that rank to HSreplays you should stop sending the games. If enough people do it they will have no more games to sell and will need to treat the people who offer them there games better by for instance allowing people to filter for the rank they have offered games for.

You can turn of some of the datasharing in the decktracker app under "options"(in the top right of the apps main window). If you don't trust that setting you can always just block the app in the firewall.
