Yeah, that is a bit offensive. If you haven't already, maybe make it clear that the message boards are made up of many stocks (including Ameritrade/AMTD) & stock traders.
Possibly include their ad on just stock message boards and a quotes page (run AMTD's quote throughout the day if that's not too much hoop jumping).
Also, make it clear it's not a zoo here (at least, not like other message boards). More of a "mature" audience, for the most part. We can chime in some iHub support words as well...
Heck, I'll speak to them (by message or phone) if it's helpful.
