A reply of yours, quoted below, was deleted by a Bitcoin Forum moderator. Posts are most frequently deleted because they are off-topic, though they can also be deleted for other reasons. In the future, please avoid posting things that need to be deleted.
May I suggest that, when the reasons are "other" that some guidance be provided so that I may "avoid posting things that need to be deleted"? The quoted email reports on a reply which was definitely on-topic, and I have no idea why it was deleted.
I understand that mods don't want to get into discussions of, i.e., arguments about, such decisions but might some variations of the boilerplate be assembled to provide a clue?
Posts which are considered as spam are not related to the topic then it will be deleted when a mod see it or when someone report it. In general your posts will be deleted if you post generic replies or saying something which has been already told even in the same thread a million times already.
