If they do leaderboards, they really need to be careful of people exploiting it. Like Saint/Beatus/Beata of the Firmament. Some of them were hardcore gatherers/crafters, some were clearly bots. I say this as someone who ranked in the top 30 among crafters. Because if it can be exploited, it will -- UNLESS it is so impossibly difficult/challenging (Necromancer title), it's impossible to automate.
