when a gambler is looking for a wager-free bonus in such a way that they can just deposit into the casino claim the bonus and then withdraw, not knowing that such a casino does not exist and if you see any casino that offers such too good to be a true offer, there is a high probability that their end up scamming the gambler.
No trusted casino or any trusted service would offer such thing. A wager free bonus that you can withdraw immediately after making a deposit, no string attached, is the same as those well known bitcoin doublers.
Any reasonable person must realize that there is something fishy when they see an offer like that because why would the casino give you money for free, what are they going to earn!
Casinos that prioritize their business to keep going must take into account every promotion they do for their members or to find new members.
giving a free bonus by making a deposit and then instantly being able to withdraw it won't be in the casino. every gambler must understand that because if there was a casino like that, I'm sure it would be a field for those who want to take advantage of the casino for money laundering or even to multiply money. only a stupid gambler would take such a bonus campaign seriously. and after they deposit money, then the account will be banned immediately.
