The only way to save yourself from scam.gambling sites is to use one that is popular with good reputation. I know it's good.to explore other options of casino but as they said, a bird at hand worth more than many in the bush, you will most likely get scam if you go to the some of these new casinos. There is also this bonus things they used to attract people but I don't get draw by such discounts. I will use my money to gamble and when I don't, I rest for that moment.
Another alternative way to avoid this casinos is to check their Twitter handles, when you see complaints a lot from people or when their account frequently get suspended, it's a red flag which must be treated with caution and when the winning stories are rampant and too good, it's another red flag to watch out for and should be treated with caution.
When anyone gambles with reputed sites the person who will deposit the fund may think as a scam though the fund may be locked due to the violation of the user. So, the user should be aware of the terms of the site and in this wa the user may enable withdrawal.
Thank goodness that you mentioned the violation of the terms and conditions. If this is truly the case, then the casino is exonerated here, but in most cases, when scam or cheating is mentioned, the casinos could deliberately do it. And if we are talking about the terms and conditions, you should know that it is only binding when the gambler signs up for such. However, when it is updated, there are extant rules that could bind the updated ones which include the receipt of the same by the gambler upon the update or the continued usage of their service.
But still, it's subject to the acknowledgement by the gambler that he has read the updated version, so it is not as automatic as you guys often thought. Only that many are not taking it up with casinos, which is why they continue to cheat them with some updated Ts&Cs without their knowledge, and anything that is not recognised by the law could technically be a scam.
For this, what you said is highly relative.
