Some fucking shitbird is out there with a password hack. Sort of an LJ virus...if you click on his URL, it posts a new message to your LJ saying only "This is very interesting" with "this" linked to his URL. It may also steal your password. I had to change my password because of that cocksmoking motherfucker.
If you see an LJ entry saying just "This is very interesting", DO NOT CLICK ON IT. It doesn't matter whose LJ it's in. If you've clicked on it, change your password immediately, log back in and delete the new entry in your LJ to make sure nobody gets hit by that one.
