<p>Harvard, or any other college, has no way to vet each application for acuracy or integrety on their own. Each applicant was asked to sign the honor code which stated clearly that a fraulent application would lead to severe punishments (rescinding acception or expusion). So if you knew someone is committing fraud, you should raise the issue with the college counsilor at your school or contact the college where the fraudulent application has been sent to.</p>
