Well the paid attack on the reputation of the casino works differently. The casino may hire a team of social media influencers to start a campaign against the casino. On a small scale, a casino may hire few accounts here to place false scam accusation against the competitor casino.
Yes, that's true, when a weak casino doesn't get as many active player as a strong one, then the weak casino starts to attack the reputation of a strong casinos with paid attacks by hiring freelancers or by paying good amounts to social media influencers. The public follow social media influencers pretty much and thus they believe in their words even if those words are right or wrong.
This is something that needs to be understood, and casino owners should be aware that this kind of thing will happen and must develop strategies to deal with it. Competition is inevitable, and these attacks will come your way.
With that in mind, if you have little capital, don't open a casino. This is a business principle. If you have weak finances, it's very difficult to survive because your money will be used up by marketing and other operations. It's very rare for a small casino to become very large without substantial capital to start and attracting a large number of customers by hiring marketers, whether influencers or other similar companies.
