It is a margin account. It is hard to see in the screenshots, but if you expand the image it shows margin requirements, margin balance, and other margin numbers at the top.
That page shows margin balance at $0.00. I don't have a familiarity with TD account statements, but usually statements are bifurcated, with the marginable securities given on one statement and the non-marginable on another. So even though it says $0, it is likely only $0 because none of the stocks on that portion of the statement have been margined. That is likely on the other portion he does not show, which would be very important to get the full story, but almost certainly would blow his argument out of the water if he did.
In regards to the "naked short selling" he implies that the reason TD is liquidating his account is because they have naked short positions and need to sell his shares to cover their own shorting. Complete BS, of course.
I agree we don't know the exact reason that TD is liquidating his account. The best guess is that it is margin related which would explain the forced selling. But there could be more to it. There might be regulatory violations, such as manipulative trading, that would lead TD to cut ties with him. Considering the large concentrated positions in several of these penny stocks, that is certainly a possibility, but unlikely to be the only, or even primary, reason.
