While I understand you believe you had a valid reason to post, the thread was in no way active. Very far from it. So continuing a discussion that is no longer ongoing isn’t very helpful. The majority of people who reply to older threads don’t generally respond to the last post, but start at the top, at the old information.
That is one of the main reasons why we dissuade necro posts, because information changes, discussions end and it is often better to start a new discussion than resurrect an old one.
