I'm a paid subscriber so making it a premium thread would not affect me, but I prefer the Zeev threads remain in the free zone.
We could ask Matt to boot them, but that's a distasteful option.
I think the best solution would be a board co-manager (or whatever it's called) empowered to delete posts by either one, as soon as they appear. Of course, that raises the problem of finding someone with the time, interest and energy to do it.
