If you think about it, the real idiots who join up can't formulate proper sentences with proper grammar, post mindless drivel, get shown the cold shoulder and yelled at and so don't come back. Anyone who can at least post something readable and understandable is somewhere over 5, and to say that they are still here and respected in some way probably means they have made some kind of good contribution that made people like them in some way, which will probably help jack their score up to around 6 or 7.
