The ones posting are harmless its the Weasels and whinners that I dislike, coupled with the ones that are everyones best mate but only to potentially benefit themselves when buying or selling (without a loss as is their right!)
However I will caveat this by saying that they are a tiny tiny minority and the majority of established and new members are superb and fantastic to meet, I have yet to meet a total idiot (I have purposely dodged the ones I know will be)
