He certainly will keep his efforts on this IP to this page.  If he doesn't, I'll block him.  I can't help what he does with the ridiculous quantity of IP addresses he may be using in the rest of the encyclopedia. Am I confident that talking to Kumioko will benefit from this conversation?  No, I'm not at all sure of that.  Given that I've talked someone down from a serious legal threat that they were serious about to the point of having retained legal counsel within the last two weeks, I also see no harm in trying.  If you're going to ANI me, go ahead and ANI me.  A limited discussion on one user talk page with a banned user isn't necessarily typical, but it's certainly within my discretion to allow.
