We may want to encourage users to boost the server by offering karma points. I wouldn't describe it as pay-to-win, because it is not giving any advantage over others. Of course, if the value is too high, it would be the case, but giving 20-50 points seems to be low enough to be considered "pleasant, but not cheating".
