I see nothing wrong with explaining why the thread was probably pulled (even though I didn't see it myself).
One of the most frequent types of spam that I find myself zapping is of the 'two part' sort, where one new member asks a question and then, just a short while later, another new member comes along with a 'helpful' link.
In particular, I've seen countless posts from people claiming to need help with their uni assignments, which have then been followed very quickly by links to assignment-writing services (most frequently based in India) that claim to provide the perfect solution to the student's problems.
Such spam threads tend to occur fairly early in the day, presumably because that's when our Asian spammers are up and about, but they can appear at any time.
So my guess is that what you saw was just the first part of an attempt at spamming the site.
