At the end of the day I've PM'd mono on a number of occasions and pointed out that others shared my views regarding the content and quality (spelling and grammar) of his contributions. He is still posting in the same way as is his right but I've solved the problem by adding him to my blocked name list so I don't have to see his posts anymore. If anything comes up that seems like it has caused a stir or is actually worth reading I can re-activate and look for myself
