Yes its fine, thats why they have affiliate program for users who can invite people to play on their site. Even its from the same ip as long as its not the same person, complying on their kyc and didnt violate their TOS then I dont see any problem. If the particular person is a relative I think the main concern for us is to remind them to gamble what they can only afford to lose and with self limitation.
Don't try to cheat casinos because they must have tools to detect IP and other activities of gamblers, on their sites and on-chains. If you invite friends, tell them don't try to cheat and break ToS.If you create your new account and don't remember what is your old one, ask for support from Roobet team. They will reply and help you with guide on what you should do. Just follow their guide, you won't be in any trouble.
It is not normal if two accounts have log-in activities with same IP address, neighbor IP address in short period and also have similar bets in same tournaments. If there are too many coincidence and suspicious activities, casinos will do further investigation.
If you don't want to have trouble about it, maybe just don't use your referral link to the person who has the same IP with you.
