Makyen @WELZ IMO, the user appears to be here primarily to promote that site. However, all 3 answers are directly relevant to each question. All questions which they have answered directly ask for recommendations of such software. By the rules SE uses for spam (i.e. that it must be unsolicited), these are not spam. If the person is affiliated, then it's clearly inappropriate, but there's no clear indication they're affiliated. They may be, but the website, and its parent, give no names.
