Missed the pictures, which is probably very good thing, but noticed that one thread has disappeared and I assume pictures were in that. It was started by the guy who suspiciously sounded like our 'rottweiler guy.' A person who has been trolling here every now and then many times. First he started by just trolling but last two times he has started with something looking like legitimate, if little sensationalised posts. Odd thing is, that he absolutely feels a need to mention rottweilers (though only by passing this time.)
He seems to get a kick from both having us fooled and posting more or less disgusting things after that.
And you are right, it is borderline scary that he keeps coming back. First few times it seemed just immature, now it starts to seem rather obsessive, especially when last time was over a year ago, if I remember correctly.
