I was wondering: to which servers do the top richest players lists apply to, because I've recently reached 500k in MT Prison (obsessive much <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f61b.svg?0" type="image/svg+xml" standby=":p">:p</object>), & I wasn't on the list?

Servers that have a cross-server economy are on the list, prison and skyblock both have separate economies so they are not part of the "Top Richest Players" list.

some servers also do not have a top list publicly available. Only Agharta and Classic are linked. the rest are each their own economy and top list.
