However, I do find a bunch that I figure are safe to kill. I use the portal page to update, most of the time, and I have it set to show me 5 random users at the bottom. Mostly this is to see the icons, admittedly (which is a whole other rant, since out of 5, there is usually only one or two that actually HAS an icon! Creepy...). I do sometimes see a usernamer that I think is cool or funny, and check it out. Two today fit the 'probably safe to kill' program though.

Still, can you imagine what a bitch it would be to go through 1090084 accounts (yay, LJ broke a million!)! 170976 have never updated, but some of those might be brand new...569712 are not considered active in any sort of way, and that is a lot to go through to determine who stays and who goes (though, if it isn't considered active in any sort of way, no posts, no comments, no nothing, it's probably safe to kill them too).
Here's what they don't understand, though: those dead accounts aren't doing anything to the system. There's no activity to them, therefore they are not 'clogging' anything. That's simply a question of server drive space, of which there is plenty, and which is easy to add. Frankly, it's the ACTIVE journals that cause the traffic problems. ;)
All the more reasons to pay for your journal.
