Scam or not that is not the issue here ,because the topic is about the closure and they are letting the players know so they can withdraw their funds before the final date, and this is not how the scammers do.
instead the site will automatically closed without notice to the general public so their funds will remain inside the casino.
but this action from luckyfish does not reflect to what you are claiming here.
Not everything is black and white like you make it seem.
Not stealing everyone's money all at once does not erase previous shady behavior.
