I am no expert, but I dont think it is best to be bullying a forum member in a meta thread complaining about rules allegedly being broken. It is probably not appropriate at all for a moderator to be doing the same at all all in any public thread.
If you dont want to deal with his rants, your choice are to ignore him (including not publicly talking about him), or put up with the rants. If you want to chastise him, you should expect a response.
