Is it safe to buy a second-hand 3DS with a publicly displayed serial number? My reason for asking is because I plan on buying a second hand 3DS but the seller posted pics of the back of their 3DS online, with the serial number very visible. I don't want to find out one day that I was console banned out of the blue. The guy from this site seems to only need a 3DS's serial number to bypass a console ban. http://le-miiverse-resource.wikia.com/wiki/Thread:199599 What's everyone's thoughts on this?
