Ok, I soften my critique given your reply which made a point I hadn't fully considered.
It sounds like the public disrespect is intentional, and it does have a purpose.. To be a good thing to do, you need to believe, among other things: 1. Publicly doing that is more likely to make him stop relative to privately doing it. (Seems plausible). 2. You're not losing something greater than the wasted time by other people observing your doing it. (Unclear to me)

It would be better I think if you could just privately charge someone for the time wasted;but it does seem unlikely phil would agree to that. I think your suggestion of linking to a fairly respectful but forceful reply works pretty well for the time being.
