Could I make a suggestion?
Isn't it unlikely that anyone trying to 'groom' young children or act out strange fantasies on this board would actually parade their age as much as the person in question has done?
I'm most worried by this thread and what it implies about certain people. But I think, looking at their responses, that the administrators and moderators are well prepared for all of this and they can be trusted to deal with it all.
My belief is that we should not worry about this too much, but keep up our guard so that if we are suspicious of activity by individual members we should report it in a private post to a moderator perhaps, and not make such a song and dance about it as has happened here.
Does that make sense?
