Could be they don't want too ruin a trustful lumi providing them specific content due too earning her trust. Would hurt more people if special customs got leaked she would doubt anyone trust or be more hesitant to do customs.
you also need to verification for an email used such as a credit card number if your account gets banned your number tied to it would also be banned so unless you have a unlimited number of credit cards numbers. I believe this is the case correct me if I'm wrong.
