A post needs to make sense in itself, without following a reference to somewhere else. A link is just a reference, as found at the foot of an article, to be followed if someone wants more information than is given.
If you just type a question without indicating that you are not posing it yourself, it is just that - a general question. You got MY answer to YOUR question.
With the minimal addition of inverted commas at each end, or putting it into italics, or putting the title after the link, with [[ ]] at each end of the whole thing, you would have shown that it was a quote from the article. That is not nit-picking, or the grammar police hounding you. It is common usage when quoting from someone else's work to add an acknowledgment.
