It is a somewhat... shallow way of engaging with fiction, but that's kind of the point. It's simple, easy-going fun. It might be that a lot of the SCP writers are a bit up themselves consider themselves auteurs, and don't appreciate people stripping back their works to their most basic elements, but at a certain point you have to accept that what you create as an author isn't real, and as a result you can't place a lot of real weight on how seriously or unseriously people engage with it.
Just to be clear, not saying that people should constantly bug authors with powerscaling questions and request, especially if they request you not. Honestly, I think it takes away from the fun and challenge of the whole thing to just try and solve issues via Word of God. But writers, especially people who write for online collaborative fiction projects, should keep in mind it's all make-believe at the end of the day.
