I am not unused to having to use the meta of an SE in order to figure out what I did wrong in asking a question, and what I can do better next time. This post is similar.
Here's the question I had asked: https://english.stackexchange.com/questions/224290/hereby-referred-to-or-hereafter-referred-to
In a google search (for me at least), my question is one of the top results.
I think using this resource (full of crappy ads and other stuff, and one of the top results), I can make a guess that "hereafter" is the right choice, but to me at least, its not immediately clear that this is the case, because it does not refer to my specific usage case at all. I think I have often come across cases where I have seen sentences like "hereby referred to...".
Here's another top link, which seems to be something about Spanish rather than English.
Anyway, the assumption had still been tacitly made that I hadn't done any research. I think most people know that a google search is much faster than writing up an SE question.
I would also like to compare my question to this well received question: Word for someone who is "quietly reliable"
Looking at that question, I am even more confused as to why mine was closed. There doesn't seem to be any attempt at research ("I am sure there is a word for this...but I can't put my finger on it") -- for instance, a thesaurus could have been consulted, and subsequently a dictionary to see examples of usage. That's essentially what the answers are doing for the question. In any case, there are similar questions to that one (synonyms for honest) on E.SE, which make it more "commonly asked and answered" than mine, which has none.
I don't intend to criticize that question, I just intend to convey that it is at first glance, very similar to my question. So, why was my question closed, and what can I do to make it better?
