I'm pretty sure separate accounts are linked via IP addresses. And the one person who will go to all the trouble to spoof his IP address consistently for each of his 10 accounts isn't worth worrying about. We're small, and we're going to stay small for awhile (hopefully), so this really isn't worth worrying about.
