Moderator, could the flying club have anything to do with this technical issue?
I don't think so unless they have their own hacker brought in to do this but that is a bit extreme and we would have spotted the dodgy code if they have done this.
The guys at vBulletin are having a good root under the bonnet at the moment so hopefully something will come up soon.
Can I just say no-one has 'forced' the site to do this over something written in any particular thread at all, I can promise you that right now.
