The court ruled that the "evidence" Frizzy submitted was unverifiable and inadmissable and not relevant. His fuzzy math has been shown to be both inaccurate and unverifiable. The SEC ignored him and told him to come back when he had something that could be construed as other than pure speculation.
And nowhere in there does Frizzy allege that 28,000 accounts are being held by two brokerages as you assert. Even Frizzy isn't that dumb. But he is dumb enough to count the same shares twice.
