I have recently written three answers with recommendations for the product where I'm a developer. In answers I pointed out clearly that I'm developer and that the product is commercial. Answers were relevant to the question and contained an explanation of how the question author can use the product to solve his or her issues. One answer got +1 vote.
Nevertheless those answers have been deleted by the moderator without giving any reason. I read the FAQ and related discussions and cannot determine the reason of removal. Can you please explain the problem?
