Why LulzSec most likely stopped the hacking spree

Apparently the long arm of the long is finally catching up to many members of the now infamous international hacking group.  For those not in the know, LulzSec is a loose band of computer hackers that have recently demonstrated their skills in computer hacking by hacking into any and everything that wasn't nailed down around the globe.  The CIA, state governments, foreign governments, banks and more have all been targets.  According to PCWorld, the top law enforcement agencies around the globe have started to narrow the group down and are moving in for arrests.  I didn'r really think they were stopping after 50 days because of boredom, they are in hiding!, lol.  Apparently they did not learn how to quit while they were ahead.
