Every moderator on here has the power to delete troll messages and there is usually at least one on here 24/7 so I don't see much threat. Further, we've been promoted on IMDb since this place started and I've never had a troll. The CT forum, which might be an attraction, is invisible to unregistered users so they probably wouldn't find much of interest here.
Since that message was posted, I haven't seen one new user from it, so I don't think we are going to have much of an issue over this. In fact, I'd like to see more new users on here to keep the traffic levels up, and I'd especially like every regular poster to go out of their way to make welcome new posters on here. We're all one big family here and we have lots of room to grow.
