(I dont recommend you to do what they did or anything like that)
The legends of SDK :
SlickShady
Maximillion
Gleeok
and a lot of other people i dont know.

Gleeok: managed to ban of his own 30 members, by taking control of Timodaichi's account, and fortunately he wasnt permanently banned

Maximillion: After being de-admined he managed to go into THE ROOM, and do the alert thing

Slickshady333: Although that what he did isnt as serious as the achievements of the other two members, he needs to be mentioned because he gave his password to a whole chatroom

P.S As i already mentioned dont do these things up there, im not responsible for any password away giving or for a deadmination or something like that
