I've seen a casino which contacted a gambler who was facing huge losses in a short time period, but can't remember exactly, because it has been a while since I saw these news here on forum. But you are right, most of them won't do this, because they don't feel it's their obligation, besides the fact huge losses for a gambler means huge profit for the casino...
On the other hand, I think a smart casino would adopt this kind of friendly measure to raise their popularity among responsively gambling enthusiasts, besides showing care and affection for their customers who will be more prone to continue loyal to their platform on long term. A mechanism like this would be really more efficient than any empty random surveys that take us nowhere...
Maybe in the future, casinos will give notice to gamblers who have used up a lot of money, especially those who have experienced consecutive losses, so they can control themselves and not continue gambling. And because the government also oversees the casinos, it makes the casinos have to be even more responsive. The government may ask for a report from the casino to find out who has experienced a loss and what actions the casino has taken for gamblers who have lost a lot of money.
Maybe surveys can also successfully provide input to casinos so they can be even better than before. Criticism from members is very useful for the casino in terms of service to its members so this survey is still needed. And from the survey, the casino can also know the level of satisfaction of its members with the service and performance so that the casino can improve it to be even better.
Alright, let's put on our "crazy hats" for a moment. Imagine a casino implementing a "red light, green light" system, akin to traffic signals. A green light means you're within your limit, yellow indicates caution, and red means you should stop. Is that too intrusive? Perhaps, but it's a concept worth exploring, no?
About surveys, I think we're missing a trick here. Surveys aren't just popularity contests; they can be gold mines of information. Why not make them more interactive? Gamify them? Offer rewards for honest feedback? Then maybe, just maybe, we'll see a shift in their perceived usefulness.
As for government involvement, is that a slippery slope? Where do we draw the line between protection and infringement? And what about personal responsibility? These are tough questions, but necessary ones.
