First of all, it is not academic misconduct to find an intermediary to send a paper. Academic misconduct includes plagiarism, plagiarism and ghostwriting. This scope does not include finding an intermediary to send papers. Generally speaking, it is because we are in a hurry, and we may not be able to wait for such a long review, or there is no channel.
But it is not particularly reliable to find an intermediary to send papers. You are likely to find an unreliable intermediary. In case your article is sent to an unreliable journal, or your academic achievements are copied, many things will come. So I think it's best not to find an intermediary to send papers.
