What are spam questions trying to achieve?

I’m just honestly confused. For the past however many days they’ve been pretty much clockwork, between 10–11pm (my time). Last night I think they were a little early.

But anyway, they are basically nonsense to read (even if they weren’t, they’d still be pretty transparent), and many of the hyperlinks even have the word “spam” or “scam” as part of the address. . . Who is actually going to click on the link?

I’m not complaining about the spam, as much as trying to understand why people are bothering to make yet another spam account to post yet another spam question that will be removed shortly thereafter by our (marvelous and diligent) mods. What can they possibly hope to achieve?
