The company need to protect their users including from phishing scams and any possible phishing sites. Users themselves never can know which sites are phishing sites and which sites are official mirror links of the casino without any official information from the casino.
I hope the Casinopunkz casino will take this recommendation into account and build up that simple page but practically very important for their users. It's helpful for users and it is also very helpful for building up the casino reputation by putting users as core place of their business development.
This could be a good suggestion, as casinos are becoming increasingly popular, and there will undoubtedly be individuals or groups who exploit this situation for personal gain by creating counterfeits.
This could clearly be problematic if left unchecked, but if there's a direct notification or statement from the site, at least we can feel more at ease. Many gambling sites, including forums, have implemented mirrors for convenience, and Casinopunkz.io could also implement this by adding additional features so visitors have multiple access options.
However, if this doesn't happen, then we as gamblers should definitely focus on the sites recommended above, as this can minimize the risk of being caught out.
