Who is actually building this library. Four boards, each measuring something different, because "top contributor" means a different thing depending on what you value.
Staff accounts are excluded from the contributor counts so the boards reflect the community rather than the people running it.
There is no trick to it: publish lineups that people find useful. The fastest route is the coverage gaps — every map page has a coverage matrix showing which targets have no throws of a given grenade, and filling one of those is worth more attention than a seventh version of a popular smoke.
