This is a fairly large casino, so it is impossible for Stake.com to lock your account arbitrarily. They have established procedures and run them according to company standards. This is actually commonplace and does not need to be discussed again. So think about what you do, so the casino says your account is indicated for bonus scams? Please re-read the Stake.com rules.
Undoubtedly stake.com is a large and reputed company and it is well known that they are not scammer. Not only stake.com but also other gambling site who has referral system or any types of bonus system will not allow them to create multiple account and also will not allow their user/users abuse their referral/bonus system.
creating a multiplie account is a scam, however the referral system created by gambling sites is to attract users to spread more information to other people about that gambling site. most accounts that get banned (not just stakes) on a gambling site are due to manipulating the referral system provided.
