Hive account@blocktrades, Hive account@minority-report and Hive account@alpha are owned by same person. All the transfers from bots (Hive account@postpromoter, Hive account@buildawhale) are payments for delegation, payment from Hive account@steemit is for proposal system development.

Even if Hive account@darthknight is Hive account@blocktrades, who cares? Anyone can have more accounts.

As a general idea, he should have asked Steem's witnesses for help. He never tried to contact STEEM witnesses. His first posting on the community was that he was preparing through the law.

Witnesses stole money from him, he have right to sue them.
