So that he can drive public attention away from the fact that he has stolen 1.000.000 NXT.

His name and personal info are out there linked with his scam, and he is blindly raging
against every person he thinks he should blame, trying to return the favor
in a rather messed up way.

His bounty-for-anons threads turned up to be rather ugly for him, so now he's attacking people that were not anonymous  in the first place, and also they had nothing to do with bluemeanie himself or the projects he was meant to work with, at the time he stole the funds.
