I think it makes a difference who starts the post. I've seen stuff advertised but the way it's done seems to make a difference. You can sell a product by calling it giving advice. The mods just leave it alone for fear of reprisal. If one person suggest a certain product that's fine, I have done that myself. But when
a post has 15 guys going X5 on that product the mods should do something. No product should be aloud that much advertising. I to wonder where the mods are somtimes.
