The best practice is to learn from your mistakes instead of repeating the same thing and putting blame on others for the same.
The better than best practice of learning from our own experience is learning from others' mistakes. This way we are able to acquire knowledge without personal losses. I believe it is the sweetest thing in gambling, being able to amass experience through the experience of others.
There are some people who try to put fake allegations against casinos but they themselves are at fault or say have lost money but can't handle it so those who accept mistakes and learn from it will never fall for such things again.
Not just some there are lots of butt hurt players that can't accept that they lose and accuse the casino of cheating them. These kinds of players should stay away from gambling platform because thay are just embarrassing themselves and making problems to other people's business.
