What is up with this question (see details)?

I clicked on one of the related questions that Fluther oh-so-casually offers whilst one is answering a similar query, and I found this question. Now, what is odd about this question is that there are several users who answered it whose lurve score is 1, compounded by the fact that this is the only question they ever answered. So, as analytical and bored as I am at the moment, I am trying to figure out if this is a coincidence, or if someone perhaps set up a few different accounts so they could monopolize the question (why they would waste their time doing so, I haven’t a clue).

I have seen other instances like this when browsing early Fluther questions, like this one, in which a new user pops up just to post a link that sends the OP to a site that advertises a lucid dreaming kit. It made me wonder if the asker and the solicitous answerer were the same person, or if that answerer was actually a spammer.

What do you all think, and have you seen other instances of this on Fluther, especially in the early years?
