It's not diamonds. More like an ad for stolen diamonds. So if you like ... there's a wall in the town where people post ads. A pram/baby-coach they do not need anymore, some kids cloths, a car they want to sell, the puppies of their beloved dog (to good people only) etc. And we've found an ad for some stolen diamonds there. But we can't remove it because it would make us legally obliged to remove all ads for anything stolen on all walls in the town. Does it make sense? I think not!
