We can take the main point of one of the leading managers on our forum here, it's very interesting and his statement can be a very validating expression of his view, no matter what the situation is he will always review the casinos run by himself to market in the forum.
I would also be interested in hearing from other campaign managers such as @Hhampuz and @icopress for their own views to add points about safe casinos to use big money.

We should not also forget that their are so many good casino that started with wonderful reputation but after a while, we started hearing about their poor withdrawal process and other cheating that make users to be complaining bitterly of unsuccessful withdrawals or delay.
There are so many good casino here that are being handled by good campaign managers like Hhampuz, Royse, Icopress, Brainboss and others.
We should also noted that good casinos can turn bad and bad casinos can turn good. All these depends on the management of the casino and the kind of reputation they want to be seeing. Some a very fast at settling users complains while their are others that would always take time.
Not everything in the market can survive and remain stable in the industry, it's hard to guarantee that kind of thing for them.
There is no such thing as going from bad to good in casinos in my opinion, unless they fix and take responsibility for their problems, it is a fact that if the problems are not solved then there will be no reputation of going from good to bad, no matter what.
