Nice to see you here and explain the actual conditions that occurred. Of course the casino must have gambling activity data for each user, maybe if there is only the same IP, this can happen if we use a public IP when gambling, but when there are similar betting patterns, the casino will consider it suspicious.
I don't know what really happened and if @theresa888 did do that, maybe it's better to just admit it. I also play at shuffle and I have never had any problems and the most impressive thing about shuffle is the speed in deposits and withdrawals.
Device fingerprints are also a good indicator for detection. Using VPN or dynamic IP might explain --or excuse-- someone from accessing through same IP address, but it's very highly unlikely for different people to happen to share same IP that also share device details.
OP, you have anything to say about this explanation from
ndumm?
