Specically, some miners have been placing CP images in the blockchain. Whether they did this as a way to hide CP material or "ironically" as a joke doesn't really matter. The end result is that some BTC are now illegal to have on your computer and it's impossibly to know if the BTC you are about to buy is one of those. I'm sure some Bitcoin-fanboy will be here soon to explain why this is a good thing.
The end result is that people can end up in jail for owning Bitcoin. ...And of course the blockchains have also been discovered to contain viruses and it's only matter of time before someone hides malware there. Heck, it could even be that the use of Bitcoins will be banned completely in some countries.
Truly Bitcoin is a glorious new currency that will rid us of problems like, being able to walk into a store and know the approximate value of money in your wallet when you get to the cashier, not getting jailed and listed as sex offender because you got some money in exchange for goods or services and it contained child pornography, and of course no longer do we live in a world where we don't accidentally find out that the 12'000€ bill you just got contains a malware program and your antivirus program just destroyed it in self defense.
