4God, i do not see inconsistency in them allowing 'sells only' and their position.
whether it is true or not -- their claim is they are protecting clients by allowing sells only and not buys - because they think risk is too high on this.
I do not see why this is at odds - when they allow sells only. because -- just for argument sake if we assume they are righteous and have good intentions, then by selling, a client is getting out of this stock and thus reducing his risk of owning this 'risky' stock.
so i don't see a inconsistency in making their claim to "protect their clients" and allowing only sells.
