Some of these people might actually not be there for scamming; most of them might be there for legit business, but they are just too lazy to do their own development, or, shall I say, they don't have enough money to sponsor their own thing from scratch.
I have come across a new casino that has almost every similarity to Sherbet Casino, and many other members were also able to see that on their site, which they advised their representative to make some changes to in order for it to reflect the new casino and don't make things look like an already existing casino.
Most times, I believe it's from the script they use, which they just bought from some random providers online, and they don't even ask them to make some changes, or they don't even care to check if there have been any casinos making use of such designs already. Such casinos, to me, create red flags and advise them to be avoided if they can't build their own. How can someone be sure their funds will be safe with them?
