If a new poster is crowding the site with adverts or nonsense then I can understand it being reported but, as far as I could make out, it was regarding pension changes which is a valid subject on this site.
Placing it all over GN is a mistake but my point is a newcomer doesn't know how the forum works e.g. when a student asks for help they often list under a number of different topics.
You might not be affected by pension-age changes - some of us are.
There've been many multiple-posts about the Bedroom Tax and various campaigns against it - I don't lose any sleep over that subject but know that many people do, so wouldn't dream of reporting a multiple 'offender'.
