This is why you don't fuck with Anonymous. Hell, you can't even get somewhere to talk to them without shields up and photo torpedoes armed. When are these "security" clowns going to realize that they are not just dealing with script kiddies anymore. Some of these dudes have been on the internets since before Al Gore invented it. They were hacking AT&T before AT&T knew what a backbone was. Now they have Ph.D's in CSE and mad skills.
Nobody can withstand a DDOS if the perpetrators are serious, but, please, this knucklehead got his twitter account, email server, and web server hacked. Password much?! What an amateur. Get a password manager and a half-way decent random generator. Good luck on LinkedIn, Aaron.
