items that can see through to wear of the prom

Why do people cover their license plate in photos on sell it pages. I mean really your license plate has public access everytime you drive or park your car. When i see a covered tag on sell it sites it makes me ask do they owe money and up for repo?? Unless you have access to run someones plates theres not much info you can get from the tag number. Stop being so paranoid people, watch your kids closer your tags are safe!!! items that can see through to wear of the prom
