I am complying with the rules

Occasionally, someone will violate a rule, and they will receive a friendly reminder before they get hammered. This is not such a case. You have no way of knowing whether or not this is a re-gift, and it is not your job to police this site. This is something between "calling out" and "calling fake," neither of which is acceptable. Do not assume the worst of people.
