I would question your ethics there. I don't believe it is the duty of a stockholder to sell anyone on the merits of necessarily buying a stock; possibly to bring the name to someones attention...but the DD is the potential stockowners duty, and they could discuss with broker or investor relations officier...And certainly not that of a stock message board character.
Conversely, it is not the duty of a stock message board character to convince a stockholder to sell.
