How is that spam?

I think you should at least have preceded the title of the original post with a "Show HN: ".

In your comment advertising your sale, you should've added a disclaimer saying that you're directly profiting from it, or at least made it clear that it is your product. Just my opinion though.

Thanks for getting back to me. Will follow your advice if I do something similar in the future.
