I Belong to a speedway forum in Australia. Because of one particularly nasty, idiot of a poster all but a couple of members left the site. When this poster was told to pull his head in he settled down for a while, hence the old regulars returned. But guess what, it wasn't long before the idiot returned to his spiteful ways so we ganged up, the site was closed and re-opened and the offender was refused permission to join again. Unfortunately it only takes one to upset the whole applecart.
