The Card ID # on a PSA graded card

Hey guys,
I see many people whiteout or coverup the card # number (i think its called something different) when scanning a card.
What is the reason for this ?
Is it not good for someone to know this number ?
I have begun to serisouly pursue my collection (as PSA graded) in a way like never before.
Comments ?
thanks

My Bossy PSA sets do not have the certification numbers whited out because I believe people cannot right click and save the images online. But that doesn't completely prevent people from taking a pic of their desktop, cutting the image out, and saving it as a file of their own. I have been thinking about going through and whiting out mine...maybe that's a good project to do this weekend. Using the "watermark" along with whiting out would be very good to do to your images.
