Spam, Spam, Spam, Spam, Spam, Baked Beans and Spam

I realize that LiveJournal is ghost-town now, that's it's become nothing but a handy delivery system to send content to Twitter and Facebook. But even though I don't get very many comments from actual humans on LJ anymore, the number of spam comments has gone through the roof in the past few months. I screen, so none of that junk gets through to readers (all three of them) but it's still annoying as hell.

So two questions for the hive mind. First, are other LJ users experiencing the same recent uptick in spam action or is it just me? Second, is it finally time to move on from LJ. Maybe even rethink this whole long-form blogging concept?
