I understand the concern with locking some of the topics on your list because they are spam magnets.
Just a gentle reminder though, this is forum is a place to encourage anyone and everyone to participate and discuss bitcoin and cryptocurrencies in general. By aggressively banning posts like these we risk becoming elitist jerks to newcomers and potential bitcoin users. I believe topics like these come with adoption and is something we must embrace.
My opinion is that questions whether silly or intelligent should be welcomed. An option we could consider is to move topics like these to the "beginner & help" forum. That way they won't be counted in signature campaigns (which will hopefully reduce the spam posted on them) and at the same time not be as offensive (to the poster) as getting your topic locked or deleted.
