In other hands, if there was anything suspicious or breaking rules of the guy play then you can be able to remove balance for reasons.
The implication is that the casino should allow users to sign up with fake/random details and later verify their KYC with completely separate details. Do you foresee any opportunity for someone to use KYC information that is not their own?
The suspicious action
is the use of conflicting details.
I don't see why this falls outside of the bucket of "breaking rules", though it seems like you're using it arbitrarily.
Does this bonus even require a deposit, anyway?
