In my opinion this term is unfair. I am not attacking any specific casino, but I do believe that if users were aware of these requirements they would be less likely to deposit their money in such casinos since there are other casinos without such stringent requirements.
That is why it is good to read the gambling site ToS even before depositing into the gambling site at all.
Welcome to scam casino. A lot of us have gone through that experience where users wouldn't really deposit anything if they just knew that the deposited amount is bound to lose.
I can not say it is a scam casino once all necessary information is on the gambling site ToS
Why not just name the casino to warn everyone here who plans to claim bonuses because more than likely that its not just you who will fall for it.
With enough people warning about them, they might just change that TOS.
It would be good if mentioned, but I do not think OP is directly referring to Amy casino, although this is possible.
