We changed the requirements to make them more clear like the SKOTM requirements change a month back.
Rather than just "we don't want you to know, you'll be on it eventually if you keep posting", the requirements are now known but with a few changes from before.
The total posts requirement was removed to not encourage people to spam to get on them and it's mostly based on current activity now.
We didn't want to make the requirements too high to eliminate people who would be called active members of the community but don't post much, while at the same time, making it easy for new members of the community to be on the high scores as long as they remain an active member of our community.
You can see the current requirements on the FAQ page:
