AK_iceman doesn't have a high score right now, but he's been very close to 3000 before and is 16th on total posts. He could potentially take the lead some day, but I can't see many others doing it.
Score fluctuates a lot. In a week players could easily gain or lose 100 places in this contest. But post count is a relatively constant thing, and even through spam it would be hard to try and pass most of the spammers. So a spammer who is a decent player could potentially take and hold the lead for a time. However it doesn't seem like any of them are good enough players
Misterman could be the guy though
6th in posts (and highest posts per day)
556th on scoreboard with a 1912.
Unless 1912 is close to his highest ever, I could see him breaking 2100. And that would put him at #1
All of that is hearsay though. DiM leads as far as I can see.
