Wouldn't that mean less shares for the existing ones? Or does the share from ad revenue only go to Global moderators and Section moderators, not Patrollers?
From what I have read, patrollers do make reasonable amounts of BTC. So that shouldn't be a problem.
I think the mod money that is allocated is capped to certain staff levels. Patrollers seem to get a max of around 2btc or so if they're very active whereas very active Globals like grue and BadBear get near or around 8btc (though I believe it's dished out by the dollar value so it will fluctuate from time to time but the payments in comparison are roughly the same)
