I agree with @smooth's actions (thus far) but believe that @smooth needs to provide a way for Mark to get back onto the site (also, did you unhide comments and read Mark's reply to @smooth?). This post was written after a low reputation account flagged his post with no explanation. I'm sure that Mark will be able to negotiate with @smooth to get his (@smooth's) flag removed (by editing or blanking the current version of the post with a message as to why) -- but doing so still leaves him at -2 (though, hopefully then, @smooth might be willing to indulge in some reputation repair since Mark is clearly a pro-community fanatic).
