It also seems like Block_Erupter and Lecture are the same. Their prose is similar.

Possible evidence: Lecture has boosted Block_Erupter's trust on this forum.

Theory: He wanted a "clean slate" to scam from and not from a known scammer like Lecture, and so used Block_Erupter. "Lecture" boosted the trust of Block_Erupter. All the credibility furnished with Frozencoin allowed Block Erupter to exploit it for personal gain with the scam that is Shares, whether planned in advance or in the "spur of the moment"
