Why you keep repeating the same thing while bitsler manually processed some of your withdrawals for suspicious activity? Lending activity is forbidden at most of the casino. Although you guys doing it as tip but you should made wager with your balance before making withdrawals. Maybe you haven't made any wager and requested for withdrawal after receiving the tip today, right? 181 XRP is 12 times more than the minimum withdrawal limit of Bitsler. Your friend should send the amount to your wallet from his wallet address, not at bitsler account.
The amount doesn't matter. Based on T&C, casino have the rights to ask for KYC if they find anything suspicious. Seems like you were aware about your mistakes and continuously ignored their warnings.
I have to say the number one tactic of any person who does anything against the rules is the fact that they are not "responsible" for anything they have done. It has always been like that forever, when someone does something that doesn't go on with the rules they end up saying that the rules are not fair or whatever and they always play the victim. That is definitely the first rule, they just play the victim and say that what they do is something normal and if the rules are against it then the rules are unfair.
Second stop is to bother people, how? They will write to bitcointalk topic, they will write under twitter tweets, they will write to instagram if there is one, they will keep pestering the casino and the users until they get what they want. These are the two steps that they take, and if they end up failing, then they give up, but it is always these two steps one way or another.
