After reading this thread I came to the conclusion that one of persons who posted an answer to my question on this site was engaging in inappropriate advertising behavior. Because his answer was the only one to my question, I wanted to warn others so they didn't fall into the same trap I did. (Namely, the answer did not provide any detailed help but essentially linked to the site selling the product. While that site appears to provide a lot of very nice detailed help, the instructions did not work for me so it represented a lot of wasted time).
My question is: What is the best way to warn others about this situation? The typical user coming to help from this site could easily fall victim to the scheme, and my question therefore provides an effective advertising platform for their product.
Because I could not find how to complain or warn others, I responded as you can see here. But I would appreciate someone in authority at the site to provide me with a proper way to complain about this situation and warn others.
