Whence all the LJ spam?

[hrj]

What is up with the LJ spam these days? I got someone posting Harry Potter fan-fic stuff on a Silk Road post. Make that two of them. I got someone with an e-mail address implying they're involved in the term papers for hire business saying something incomprehensible on my "recent changes in LJ" essay. I mean, I delete-and-ban, but I don't get what the purpose is.

The classic reason is that they try to boost the Google page rank of their pages. Many of my recent LJ spam has contained hidden links.

Another point is that spamming is cheap, and thus even a microscopic new-customers-per-spam ratio gives them good income.

I sometimes get kanji spam with no links in evidence. I don't know that the reason would be any more obvious if I could read the language. It's weird. (If links are present I assume it's an attempt at Google-boosting.)
