Thanks very much for the feedback. Fair play if you didn't find it funny - that's clearly the correct standard by which -Js need to be judged. Anything below is not trying to change that (an impossible task) but merely to clarify my thinking in case of any residual confusion.
I will admit that the jokes are not intentionally bad. Some are intentionally lame, but I am intending to be funny (in various ways), so anything that fails that test is an indictment of my sense of humour :)
That said, I am intending at least some level of subversion of the tropes by providing an in-universe explanation for their existence, and by taking aim at mainlisters for my examples, and not (for the sake of argument) SCP-100000-J.
Unless there's something I'm missing
I'm not sure there is, necessarily. Although I would point to the J-list title as a nod to my overall aim here.
