There could have been changes in the system that made this happens else we would have seen such high score by now. What I also do not understand till now is if playing on multiple tab was the offense of those users who were banned from the tournaments and if Duelbits even specified that as an infringement to the tournament. Maybe the new users are playing fairly and according to the rules which is why we are seeing the lower points as I don't want to believe its because of reduced interest in the tournaments. Meanwhile making profits from the tournament will not get one banned
Top player was banned so new top player that typically wagering lower amount than previous top player now get the top spot with their normal wager.
Think about the previous top 5 now gets the top spot that wager less before. There’s no need for them to wager more if the competition is less due to banning of competitive player.
I doubt multiple tab will be removed because there’s nothing wrong to do that. It doesn’t affect the game rather just give the player the advantage to wager quickly.
