Even if the support works perfectly in the casino, there will be people who, frustrated with failure, will accuse them of cheating. Of course, anyone who plays for a long time knows that such things happen, but remember that the gambling industry is a very large and ruthless market.
I wouldn't generalize things here. The fact that there are many gambling sites trying to scam their customer doesn't mean that the whole market is ruthless. Honest sites struggle for years to build up a good reputation, and they should not be treated as one gang with scammers.
I am sure that the besides frustrated losers, are there rival casinos with their tricks. Im sure they not only run campaigns to advertise themselves, but they definitely try to slander their competitors projects. When the action is big and intense, something like this can real make difference in players confidence to the casino.
Not everyone resorts to such shameful activity. Only scammers do.
