This dumb as hell as I specifically posted this video in the scammer thread this past weekend.
Dude a scammer, a high school drop out who never even attended college and was arrested for bank fraud.
Second what he said is wrong if you pay off your student loan it doesn't stay on your credit report as bad. It will be on your credit report as paid off account which means it does not hurt you in any way. Outside of the initial hit of an account closing (no more than paying off and closing a loan for a home, car or credit card account) then 3 to 6 months latter your credit score will go up.
