The reason why casinos have stopped none deposits bonuses is because of abuse from gambler's, I remember when one new casinos that came on board this forum made a grave mistake of giving new accounts without kyc free bonuses and to make things worst for them, they even made the bonuse witdrawable and that was it, the went bankruptcy sue to heavy abuse from bad actor's.
That is what they call a rookie mistake.
What is the name of the casino, I would like to know how they were able to recover and get back in business.
They were not able to recover as far as I know, Though I forgot the exact name, I quite remember about that casino that gave signup bonus in this forum. When new users found out that they can immediately withdraw the bonus, they quickly abused the signup bonus. That new gambling platform didn't even lasted for a week and closed their operations.
Those were the days where online casinos are at its early stage. As the casino industry learns, you can't find a "no deposit bonus" now. Most promotions now requires some complex requirement before you get the bonus.
