For someone keeping their MK7 oem stock, there is no real concern to posting your license plate, except for the occasional pesky axe murderer or ID thief, who may have their ways of finding victims via license plates. There could be programs and ways available on the Dark Web that can do things most of us do not dream of. One would assume many axe murderers etc will hang out on the Dark Web.
However, people who do warranty-voiding mods will want to blur their plates. Otherwise, you're announcing to VW Dealers: "Hi there! I have mods that void my warranty. If I bring my car in for warranty service, you will know me by my license plate I posted on a public forum."
Your next question or comment will be something like: "Oh, c'mon, VW dealers are too busy to watch forums." To that, I'd say, you are right, some % of time. But what %? It is a FACT that VW dealers HAVE used forum info to avoid honoring a warranty. Search for it. Point is, why take the chance, unless you are certain you will never mod? And, you know...axe murderers. Maybe you pack a pistola, but then you'd have to shoot everyone you see carrying an axe, before they got within swinging distance. There could be some legal issues arising from that, unless you ran away, and were lucky. Do you feel lucky?
