"Still a man hears what he wants to hear and disregards the rest."
It’s very difficult to convince people like that on the basis of just a say-so, because they don’t want to believe you. That would mean that they’d been doing a very bad thing, and it is easier for them to believe you are lying than admit they were wrong.
And besides, publicity is a double-edged sword and you can never quite tell which edge will wind up cutting where. Keeping in mind who comes here, releasing sales figures will only deter people who come, read the boards enough to see the posts, and haven’t already committed themselves to a decision. The regulars here are already convinced, and so are the pirates. And the other effects of posting sales figures are totally unpredictable.
Someone who is somebody could see the sales figures and decide against stocking Pea Pri products on that basis, either for not enough volume or for the act of posting sales figures.
Conversely, someone who is someone, and a fan, could see the sales figures, decide Pea Pri needs help, and come to the rescue. (This is less likely.)
Neither one of these outcomes is controllable. Nor are they predictable. That’s not usually a good thing.
