The alpha mechanism is really disgusting. If you can't catch up once, you can't catch up the next time. The ones who can benefit are always the same group of people. So users who missed a few days are not considered people, right? It's a complete waste of time. The last digit lottery is also a trap; isn't this obviously encouraging multiple accounts? Just inflate the scores a bit more; can't you just enable a multi-person lottery mode for scores above 100? Why are users with scores above 100 not considered active users?
