I highly doubt if there be any chance for them to wash off the shame and restore their name as you put it, this is one beautiful thing about reputation and I love it, that is the fact that it is very difficult to build and extremely easy to destroy, this is why those who have it already, guide it jealously so they don't lose it.
Even if this casino decide now to pay back all the money they scammed from their victims, back to those they scammed it from, still, their reputation can never be restored back to the level it was in the beginning, not even close, except they decide to close everything, lose everything and start afresh under a new identity and new brand, and even at this, if the community at any point find out that the new identity and brand has a link with this old brand, the reputation of the new identity and brand will be automatically destroyed as well.
