All of my hacking experience is behind me and I'm sure most of the methods no longer work. It was fun while it lasted but that was 10-years ago.
Having said that, since there is no official leader, any hacker can take down a Twitter account and claim that it was pulled off by Anonymous and thus the group will live on.
Based on the type of attacks they have made, it sounds like they are in the US. I was OK with the attack on Sony and a few others they made, but putting innocent people at risk is nothing to be a fan of.
The hacks attract a lot of attention from folks like us. For many, Anonymous is making our childhood dreams a reality and as part of the blackhat internet world, we feel like part of the 'team'.
Most of us are smart enough to see the long term consequences.
The silent leaders of Anonymous will come down over time. Greed, glory, and fame will get the best of many and agenda's will no longer line up. Members will turn on one another. New groups will form and hacking will continue.
That's my take...
