I agree Colin, the trouble is that FlightAware doesn't have and isn't willing to devote the time and resources to baby sit clowns on a daily basis. The people that do this just want that gold star next to their name.
It's all about simple satisfaction for simple people.
It's too bad that everyone has to wade through columns and columns of repetitious and boring shots of the same planes from the same angle with no information, or out of focus and fuzzy shots of planes we've all seen hundreds of times in our lives. Some people seem to think that if I shot it, it must be great and it deserves to be on the internet. Real photographers whether they're an amateur or not, will tell you that out of all the hundreds and hundreds of photos that they shoot, only a small minority of their shots are really good enough to share online. They weed out the not so good ones and post the best of the bunch.
Until FlightAware devotes the time to police these clowns, we'll have to put up with the waste of our space and time.
