Good catch! You should flag this as spam since it is clearly spam. The OP is trying to hide their spam in a valid-sounding question.
Actually, for such hidden things, a custom mod flag might be a better choice. Explain that it is hidden spam. Otherwise, the mod who handles the flag could easily miss it.
In this particular case, I found the text of the question in a forum post here. The spammer simply copied it and added the spam link.
I've now deleted the post, thanks for bringing it up.
