"Hey buddy, I need ya to run a tag for me when ya get to work tomorrow."
"No problem. What's up?"
"I saw a great set of wheels and tires posted on our Vehicross forum I want to try and score. The guy lives not too far away, but I need an address. At the very least I can easily get his roof rack that'll get me $500 on eBay."
"Sure thing. Just drop off a case of beer this weekend."
If it cost $200 and took a week to block a plate from a photo, then why bother. It only takes a few seconds, so why not do it? What do you have to lose by blurring the plate number?
