Obviously JF/W&R can be classed as a troll.
There are one or two others that I remember, such as one thread that was clearly started by a young male with nothing better to do except try to stir things up on here, along the lines of "I'm a sahm with a ?yr old ds, I like girls and want to meet some, but I don't know how to tell my husband". The whole tone of the post, spellig mistakes and everything just cried out TROLL!! I'm not sure anyone fell for this one and actually replied.
Which other ones can any of you remember?
