You're right. We know for sure Clayton didn't understand the divvy process, ex dividend dates and who sets them. That's proven in his news releases.
If the TA had sent out divvies he shouldn't have, they would be included in his OS count, but they aren't.
I don't think it's going to be the TA's job to get back any divvies that might have been improperly issued by brokers, those of course would have been FTD's months ago, it'll have to be FINRA, Nasdaq, DTCC or a combination of those entities.
