No, the rule is about plagiarism
The problem is, in the thread I linked it seems they give you a nod and you reply with “all good”
That would be, at least to me, them acknowledging source, and you giving approval.
Regardless if you were made aware after the fact there is a rule against plagiarism.
Which to me applies to more series things like digital sigs etc, but I mean I guess could apply to copy/pasting format/wording, and in your case exact post.
So I ask again, what is the outcome you seek?
