I understand your not wanting to provide free advertising, but you fail to understand how you go about it diminishes the value of the firms that do spend money with you. By censoring the likes of def, you call into question anything paying sponsors have to say. I for one am bitterly disappointed in your decision. I have two options available. 1) to leave the board, and 20 to refuse to read any post from a known sponsor. In either case you lose, and so do the people who pay you.
