Yes, this works very well.

Instead of seeing any of Nerdmann's annoying comments, all you see displayed under his name is: "*** you are ignoring this user ***"

I would also ask the moderator to review Nerdmann's past comment history, and observe how they are designed to do nothing more than intentionally antagonize the other forum members.

I would therefore ask the moderator to step in, and REMOVE him from these forums.

If other forum members request the moderator to have him removed, I'm sure the moderator will oblige.
