So our favorite haxors decided that they had taken enough shit from b, the place where they undoubtedly got their start, that they decided to take 4chan down a peg or two. There is currently a DDoS raid on 4chan being executed by Lulzsec in retaliation for Lulzsec not doing it for the lulz, but for political motivation. b has no political motivations aside from trying to shock your ass into thinking they are depraved lunatics.
They/we are, but lulzsec turned anon into something greater. They hacked the U.S. Senate, the C.I.A., the Spanish Police, the government of Turkey, Syria, etc. We are seeing internet vigilantism at their best.
To be clear, b has been banning/turning over IP addresses of the sickos who post CP for a few months, so it isn't quite the cesspool it used to be. When they took issue with the political nature of lulzsec's attacks however, lulz responded. 4chan is now down due to a massive DDoS and condemnation of their attacks on children.
Sucks when your own methods are used against you instead of a fourteen year old girl eh?
What I'm saying is that LS may not be the "good" anon, but they sure as hell are better than that from whence they came.
The revolution has begun, and there will be no retreat, no surrender. There are no leaders, there are no members, there is only legion, and they do not forget.
Sleep well. You are protected.
