Ok so you got banned from HLH. There are four reasons this most likely happened:
1) Normal consumers don't do what you do. Normal people go forum to forum asking questions of many types. Expressing opinions on many products. Researching solutions, and helping eachother. Simply put: They're random. You have visited several websites and focused heavily on one product. A product nobody's ever heard of, that everyone knows won't work. Not only do you focus on it, but you go site to site registering new usernames and starting more and more threads on one thing: that product (which nobody's ever heard of, and everyone knows does not work). That isn't how a normal person acts, on the average, on forums like these. I speak from nearly 8 years of experience.
2) The legitimacy of the product is another factor. When someone doesn't act like normal forum members, but instead has an abnormal focus on a product, and that product is also something that is almost downright silly in nature, that person's motives are brought into question. When someone who nobody knows shows up on the scene and begins talking about a product, that's one thing. When that person begins to develop an abnormal focus on one product, thats something different. When that product is nonsense, then you're going to arouse the suspicions of everyone around you.
3) Forum owners and moderators pour a lot of time and effort into doing the research and helping point their users towards logical, scientifically backed products. Everyone is free to try what they want, and talk about what they want, but cross posting about one extremely silly product across multiple sites only makes you look like you are tied to the company selling it. Understand that the site owners didn't make their site so that people affiliated with nonsense products can undo all their hard work and confuse their users away from what will actually help. Im quite certain site owners don't consider your posts on this silly rubber magnet product, to be adding to the intelligence, or general benfit, or increasing the education of their users, and that's a big factor.
4) The last factor is that you engaged these guys in arguments. Even the site owner. Some comments were made. Maybe you quoted someone incorrectly, or changed what they said to make them look more sinister, or ... whatever. Probably not a good idea. In their eyes you were already doing something that seemed dishonest. Arguing with them and changing their words or quoting them incorrectly just paints you as a dishonest person in general, and solidifies their suspicions about your motives. That's why you've been met with skepticism, annoyance, and even insults. People either think you are extremely gullible, or they believe you are knowingly try to sell something that doesn't work, and make a buck off the unsuspecting.
Your best course of action at this point is to educate yourself on the causes of hair loss, so that you can begin focusing on products that might actually help. Your second course of action is to stop talking about this product. If you're really just a steel worker from a small town in Pennsylvania, then I can't think of any reason why you'd be so heavily focused on a rubber magnetic roller. Based on the 4 above things, I am suspicious as well. You're just not acting like a normal, unbiased person acts.
