Recently an answer I posted to this question was converted to a comment by a moderator, apparently because it was considered a non-serious answer. I posted it as an answer rather than a comment because I found the image match and the reasoning behind the answer compelling, even though the answer was not in-universe for Superman. I am frustrated by the change to a comment because it misrepresents my intent; I was not making a joke, I was trying to logically answer a question that probably has no in-universe answer. I knew the answer wasn't conventional and that I'd take my lumps in downvotes from some members, but I was surprised by an outright deletion.
Should I give up on posting unconventional answers on scifi?
When should moderators convert answers to comments and when should they let the upvotes/downvotes run their course?
Edit: The converted answer was
Clearly, it is the Nexus energy ribbon from Star Trek: Generations. Since the Nexus is timeless and connects all possible realities, there's no reason for it not to be cruising around in the Superman universe as well.
