Does dark chocolate spoil

While white chocolate *can* spoil by developing mold, it is very uncommon unless you have kept your white chocolate in a humid place for a long, long period of time and/or it has been poorly wrapped. White chocolate is particularly more unlikely to develop mold than milk or Dark Chocolate because of the large quantity of sugar used to make it.

However, white chocolate (because of the cocoa butter in it) *is* very prone to picking up ANY smells that are nearby it. For this reason, it's not recommended to store it in your refrigerator because it will pick up refrigerator smells and affect the taste. So, while white chocolate stored in this manner may be safe to eat and not spoiled, you may not like to eat it if the flavor is compromised (ewwww :p)
