I'll try again. Some folks like to post things that they may not want others in some authority to know. For instance, you might not want your insurance company to know that you use your car for HPDE or time trial events, or maybe you like the sound of your de-cat (AKA test pipe) on the street (a federal offense), or that maybe you beat a Mustang at a stop light derby the other night. If you like to post about such things, posting a pic of your car with the license plate visible in the same forum, under the same forum ID, is probably not a good idea. Of course this may not apply to everyone that blanks out their license plate, but it certainly could be true for some.
It was some years ago, so I don't have a link ready at hand, but I do recall reading on a forum that a dealer service department refused warranty repair based on evidence of track use from an auto forum (not Lotus). I also seem to recall someone getting insurance coverage refused for an incident that happened on track, but that minor detail had been left out from the owner's claim (could be construed as fraud), and the insurance company found evidence of the track incident on-line. Both of these scenarios seem unlikely, but why take the chance? If it's online, it's easy enough to find, only question is if the adjuster or service manager bothers to look.
I have to agree that worrying about someone stealing your car after they tracked down your location based on a pic of your license plate is baseless, but why assume that's the reason the owner/poster did it?
