Last night (at midnight EDT), the webcomic xkcd (xkcd.com) updated (the specific comic in question is http://xkcd.com/465). The mouseover (title text) referenced a hypothetical article title, "Russians cut apart and reassemble dogs" in reference to this: http://en.wikipedia.org/wiki/Experiments_in_the_Revival_of_Organisms .

However, a Google search for that _exact_ phrase (without quotes, though) (http://www.google.com/search?q=russians+cut+apart+and+reassemble+dogs) returns a _lot_ of spam – for me, results 1-4, 6, 7, and 9 are all spam – that all seems to have been created (according to the timestamps in the search results) within hours of the comic being posted, as if the spammers knew there were a ton of xkcd readers wondering about this experiment (the way it's stated in the title text, it sounds like the title of a specific article).

Interesting how responsive (and probably effective; I clicked on the first result without even looking at the result page and without noticing that it was spam) spammers seem to have gotten.

Any ideas what could have triggered this? Or am I missing something, and is this phrase "older" than I think it is?

Is it possible that the text was included in the xkcd RSS feed? I know some types of spammy publications automatically copy feeds to create content...
