@TheKalaakaar As moonboots said mentioning addons even payed ones is fine, as long as the post make a minimum effort of actually explaining a workflow or at least basic steps to use the addon.

In the post you linked there is a minimal explanation, but I seemed enough to justify the existence of the post. If you ever encounter an answer that you feel is just promotion, or disagree with the decision taken, you can always rise a flag as "Not an Answer"
