It's kinda frightening how fast spam networks adapt and evolve. And I think a lot of people don't realize that the goal isn't to deface an individual journal, but to collectively get as many links into their home website (which will boost the rankings in search websites) as possible.

If you've ever wondered why sometimes you get spam that's nothing more than a string of nonsense characters that look like somebody walked over the keyboard, for instance, that's the reason. They do a test run of gibberish that's easily Googled, and hit (say) a million pages, then wait a month and Google the gibberish and see what kind of visibility they get, so they know what kind of Google juice a URL in that location would give them.
