I've been having a horrible experience on a website forum called HousePriceCrash.com.
I happen to believe house prices will fall significantly, which is why I went there to find out more, but many of its members behave in such a paranoid and hostile way towards anyone who dares utter any dissent towards their very particular and obsessional group beliefs. They repeatedly accuse other members of being undercover operatives for the property industry - they seem to have a grandiose idea that they are so dangerous to the property industry that the industry wants to damage them by sending undercover operatives to 'troll' their forum. They almost seem like a weird religious cult that does not tolerate heresy amongst its members, or else they will be publicly degraded and excommunicated from their church.
It seems populated almost exclusively by men, I think. One of its members seems to have become obsessed with me in a nasty way, and even though I have never responded to any of his repeated public comments to me and about me, he won't stop pestering me. He gives me the creeps. I know it is only cyberspace but I still find him a bit scary. Does anyone else have any experience of this forum?
