If you report a post, a mod will look at it. A mod might get back to you about it. Usually not. Later, you might notice that a post has been edited or you might see that a warning has been issued. Or maybe the mod will look at the report and not see anything in violation of the rules. Like last night.
The poster has a liking for a specific brand. Not illegal.
I checked his posting history. He posts other things, too, so I don't consider him a shill. A fanboy, maybe.
The brand he likes primarily sells on their own website, though I saw the brand listed for sale on at least one dealer site, as well. Many manufacturers sell their knives on their own website.
If that brand sold other brands as well as their own on their website, I would consider them a dealer. But I only saw their own knives for sale on their site. So I consider that a straight manufacturer website and not a dealer. We allow folks to reference a manufacturer's web site.
