ND wasn't hacked. It was flooded. It is just a coincidence. ND was flooded by Tentrillicon, aka fAllen, aka R3lm, aka Wolf, aka Impulsive. Impulsive fakes clans (Ex: EA, DC) in order to get attention. He also creates clans constantly (oG, gE) to get attention. Sadly, he also floods servers under these fake clans, for more attention. He is also banned from many servers in ET for using exploits. The recent flood was not caused by the actual DC clan; it was caused by Wolf and his fake DC clan.

e2: Also, Wolf is known for faking servers. He's faked EA servers in the past, and he is currently faking DC servers. If you see DC*NoDownload or DC*Beginners on the serverlist, it is fake.
