It is more usefull then hacking hotmail etc, but that was not my porsonal reason for calling it a waste of time...
I think it's more a waste of time to spit bullshit about firewalls sub7 nessus and whatever and after that comming to a conlusion it's impossible because it get's DoS'ed and blablabla and then calling it a waste of time.
If you don't know were the hell it is all about, don't go talk like a dumbass or even worse, respond to a dumbass and say he's right... Ow well... now I even start to sound arrogant or something.
