At one point, people were kept from posting more than once in x amount of time. Can you keep people from refreshing more than once per minute or two (or three or four or five) except for live scores posters? Refreshing that often is obsessive anyway. Tension can be good. Make 'em wait.
I hate to lose the scoring threads. Even if the thread is closed for all other posters til the match is over, at least the record would be there.
