After soo many scam accusations on duckdice, I still se people depositing money on their website. Well I don't know much about the scam but the people who have given him negative trust are the most trusted people in this forum. So I would probably stay away from duckdice
The reason why people still deposit their BTC is because Bitcointalk isn't the only bitcoin forum. There is Bitcoin.com forum, Bitcoin Reddit and there is the organic google traffic.
People also don't always speak english so they don't understand when a site is having issues. To play dice you don't need perfect english, since its mostly numbers.
The people who gave negative trust didn't really put their attention into the case.
And since people are still using DuckDice it means that there is nothing shady, dice is a simple game, you deposit, you win, you withdraw. DuckDice issue was with Bonuses (and we have refunded users deposit at full amount) not the core features of dice itself.
