I think there are still some Google Play Booster games out there that give non-zero exp values, like e.g. https://www.exophase.com/game/clicker-increasing-the-level-android/achievements/. Maybe, it would make sense to also block all Google Play games with Clicker in the title?
Seems like a good idea. I added any games with Clicker in the title to the exclusion list (will update on the next calculation). If there are any games this removed that should be counted, let me know and I can always whitelist them.
