This question already has an answer here:
Does answering all questions about a product that I'm working on is considered self-promotion? I'm asking because of this part in FAQ:
If a large percentage of your posts include a mention of your product or website, you're probably here for the wrong reasons.
And is it necessary for me to disclose my affiliation? Note that the questions are directly about how to use the product and I'm not suggesting my product as a solution
