Play him at his own game
Borrow someone's sockpuppet account for a couple of weeks and post whatever you would normally; log back in as berk occasionally to post something like "Oh, I feel bad, I didn't mean to hurt him but it wasn't working" and just keep up the pretence until he stops paying attention.

I can't be arsed
and I shouldn't have to. If he continues to read my posts however I may consider it.

You're right, you shouldn't have to
