Here’s a fun story from someone at Gaming Unity:
“when I booted up my 3DS and one of the built-in games to find a photo of the previous owner smoking weed. This didn’t really bother me but could have definitely lead to some awkward questions had the 3DS gone to a child, even more so if the previous owner had decided to take some more illicit 3D photos. I contacted the CEO of Game / Gamestation to let him know of this and asked if it was their store policy. As expected, apparently it is store policy to clear the data from all consoles that are bought. I was assured that the importance of wiping all data from any console they buy would be stressed with their training department. As well as that, I received £25 compensation which is awful kind!“
Moral of the story? Buy a used 3DS, and take a 3D picture of your buddy taking a massive bong hit, and you’ll get cash compensation, then if you send your story+picture into Fucked Up Games, we’ll write about you, seriously; do it.
