Most of us don't sell or get anything from sales. Some of us try everything that looks like it has potential and form an opinion and when one of the group that does this has a good or bad experience I like to hear about it. Of course there are a few people that push some lower quality stuff but it becomes obvious who they are and they are like a tick always trying to sneak up and bite. As far as I know there is no way that much can be done about it they just come back under a different name and clutter up the form.
