How can I get LAN to stop bullying me for being mentally ill?

I've blocked him, but he somehow gets through the block. Reporting him also doesn't do any good. It's been going on for years and I'm really sick of him. He makes me nauseous.
Update: Apparently, I'm not the only one he's bullying, here's a question from someone else...

Update 2: Putting blame on the victim of abuse is no better than what LAN does.
