Yep, there are definitely risks in using a VPN to access gambling on various sites, and users should be aware of this. Even if a user clarifies this issue with the casino support and gets a positive answer about the use of VPN, it doesn't guarantee that the casino won't change its mind or change the ToS at any point in the future.
Most especially when they discover that such is no longer working for their own advantage, i know how gamblers could be so mean in making attempt to override on the gambling platform network and try to bye pass some certain functions or restrictions on them, which we also know that some can cheat on their system through this, we need to go by the way of making things easy for us and the platform we are using to gamble by not starting what may implicate us later in future.
Most of the users typically target abused of casino bonuses such as welcome package, deposit bonus and etc. which they do unli try by creating multiple account through the use of the VPN. Some users play from restricted country which they are risking their money by using VPN to hide their location which useless since casino can see whether a user is using a VPN or not.
In general. Using VPN to take advantage on casino will not gonna work. They are the users that we frequently saw on scam accusation thread playing the victim while in reality they are trying take advantage on the casino.
I like @dwyane36 mention, Casino can change the ToS anytime without any notification. This is enough reason for us to check ToS regularly before using VPN.
