People should understand that as long as there is a blockchain there can be stored illegal stuff there forever. And the point of a blockchain is this "forever". This is the same for Datacoin, Namecoin, Bitcoin etc...
That makes a lot of sense GreekBitcoin, but keep in mind that DTC is the only coin that focus on the blockchain storage potential.
Nobody looks at Bitcoin, Namecoin and think of it as a place to storage files, so nobody gets worried with illegal content.
DTC needs to deal with this fact because storage is the essential part of how people perceive the coin.
