Based on OP's post he already made some research and he is fully aware of his account will be locked if caught violating the casino's TOS, his post is an example of what will happen to you if you do not follow the casino's TOS he is ok losing his $1200 if there's no chance to get it, well it's good that it's ok for you but it's a different story if it's $30k or 45k or an amount that you want badly to withdraw.
He expects it that's why he don't deposit big or he didn't play more till his winning became really huge because he know that it can be a waste. OP still tries his best if he can get out with the money that he currently have. If he can get it well good for him and pretty sure he will attempt it again on the same site or into the other site but if it did not work, he might moved on and wont do the same thing as its crazy wasting money for nothing.
Some people went thru this before and they are sharing their stories but I think it is not guaranteed that you will skip that part once you hear and read it because at the end of the day you are still new to it and you can still make a mistake.
