There are still some weaknesses in the gambling sites, but what can be done about them? There is a lot of talk about cheating and arbitrage betting. Perhaps rightly so, but what can be done about it? That hassle with table tennis and cams, that does not make sites happy. And then with corona you also had a lot of competitions that were manipulated by the bookies. There are too many matches to monitor all of that in time.
Weaknesses in gambling sites will increase and become the next target of hackers who want to take advantage of their bugs. If you don't want to experience bad things like what you have shown, you should choose a gambling site that has a good reputation so that it is hoped that no cheating will occur. Maybe the bookies can manipulate the results because we don't know 100%, but that will not happen at the recommended casinos because the casino really wants to provide comfort in playing gambling to its members. But if we talk about the vulnerabilities in gambling sites, it will depend on how the security team will secure their sites from hackers.
