This happened to someone I know very well, but I found this to be too cruel, different IPs on the same device shouldn't cause this ban, what do you think?
There are some gambling platforms that pray that users make this mistake and use the opportunity to sit down on their money.
It seems to me that this is quite a controversial issue. Using the mobile network you can get an IP address that was previously used in certain activities that are not allowed in the casino.
The casino will not investigate who broke the rules with that IP address - so I quite understand this practice (on this forum, you can get banned immediately after registration, if you use an IP address from which banned activities were noticed).
But on the other hand if you are sure you did not violate the rules of the casino and got banned, that's a different story.
