You could complete KYC and still get ban by some casinos. This is just too complex to figure out and most time I don't like it when a casino try to detect multiple accounts only through AP address which I know can always look the same if we must judge from that.
Casinos have different tools they can use to detect and suspect multiple accounts on their casinos and I don't opt in to the use of IP address. That is an old pattern that is not so effective especially in a school environment where students connect to general WiFi to complete assignments and do other things.
I also don't buy the IP address fashion used by online casinos in flagging customers accounts on alleged multiple accounts default. There are customers that have being victimized innocently through that's assessment. I think using other tools into finding a multiple accounts situation by a customer can really be helpful in solving the problem of casinos wrongly banning customers accounts based on IP address suspicion.
