how do you know he is the one that hacked keinett?
how do I know? go check his only video... it's just simply too obvious.
the description is the thing "we are anonymous, we are legion, we are akojiodbhvgfuysiu.. etc"
Also, he only seems to know how to DDOs minecraft servers.
ALSO, as soundtrack, he used some kind of weird "music" that show exactly the type of immaturity that had the guy who hacked us.
His video was made a little while ago, now he might have got some better programs that allow him to do as much damage as he did (taking Owners powers, editing server files, etc)
For now, it's him, I'm sure of it. If you can proove who is it really, go ahead, I would like to know that.
