The reason is the layout and many data show up are gonna make the site have heavy data process, make you lagging while accessing the site. They can only show up to 40th place. Is also for the same like (Recent bet and other things).

There is no need to show up all-player due to this recent just cut the maximum they can show up + with your current standing. Remember, your account login forever is already without logout already make the site heavy.

If they add updating a list for up to 5000 people who are always needed to be update every second, I bet is gonna to freeze ~XD.
