I dont think faucet will bankrupt the casino as long as the casino knows how to offer it effectively. Not all players in the casino claim the faucet all the time, who on earth will do claim small faucet all the time? The current situation where there are few casinos with faucet is that it is no longer effective promotion/marketing tool. Other reason can be because of the big number of abuse in the past when many abusers tried to make money from faucet with no intention to gamble at all.
or industry on which it would be understandable that they cant just let it happen on letting people do claim endlessly which is really a huge expense for their part.
We cant really deny that there are really people who do tend or try to abuse faucets but it is really just that standard that there would be limits on claims
+ having that protection against bots which is really that typical security that would be set out.
