weaknesses will always remain. And players who try to exploit this will always stay, you can't do much about that. You can draw up a policy policy, and in combination with a kyc policy you can put a limit on a certain player, for example. That way it becomes much less interesting for a player to continue cheating.
There's always an issue on any gambling site, just like my experience before about my withdrawals considering that they are the top betting site and yet they are far from being perfect which I think none on any site claimed to be perfect. Vulnerabilities are always there since hackers are really great as well, imagine Binance got expose to those hackers, what more the other site especially in gambling where security is the main concern.
Which gambling site would this be? because you mentioned as a top betting site and you experienced issues so i think there is nothing wrong to tackle that problem here so we won't think that you are only making stories here.
but of course you are perfectly correct about Gambling sites all of them has issues but at least in legitimate site we can only experience small issues or some stuffs that isolated.
and this is normal in every business i guess?
it is impossible to a big business not to have some problems in their Businesses because that will never happen.
There will always be lapses even in huge and reputable gambling sites. We might experience inconvenience or issues but if a gambling site is reputable, we should expect that they would always do something to fix it. I've experienced the same thing as well but it's an edge that I'm with a reputable and trusted casino.
