The issue is fundamentally one related to the Hot Network Questions feature. If a question gets a certain number of hits organically, it automatically gets promoted across the Stack Exchange network and ends up going viral. I've had this happen myself: gaming.stackexchange.com/questions/338283/…

@Mokubai: Not a perfect solution (because we lack better close reasons), but I'd say that's a good idea nonetheless.

Perhaps we should just leave the question closed, with a note that the question lacks adequate research effort? Despite the community thinking that it's a bad question, I think it's valuable enough for readers at large to justify a historical lock.
