I'll quote another bit of what I said: the members of Anonymous who are doing the real heavy lifting are probably not fools.

Anonymous is anybody that wants to be Anonymous, including people who have never been Anonymous in the past and will never be Anonymous in the future...but, quite a bit of what Anonymous has done required specialized knowledge and experience and intelligence. Those are the people the FBI would like to identify, and they're also the people least likely to be identified by a data leak like this. So, a leak of Anonymous IP addresses is really probably a leak of kids who haven't actually done much damage and a handful of Tor exit node addresses representing the people within Anonymous who know how to wreak havoc.

That's part of the strength of Anonymous. If there is a crackdown of any sort, it will snare a bunch of innocent (or close enough to innocent) kids, and miss all of the real targets completely. Law enforcement could only pin the blame on dumb 15 year olds so many times before it begins to seem ridiculous (especially since if they claimed to "take down" Anonymous by doing so, there'd be a slew of attacks by Anonymous just to prove no such thing had taken place and the people they'd arrested were innocent bystanders).
