Staff don't get paid per report per se, but there's a payment algorithm that takes several factors or 'mod actions' into account, but only theymos knows what those are so staff can't game it. Obviously handling reports will be one of the main factors and probably moving threads/deleting posts will also likely be counted in some capacity. Payments are capped though, so even if I spent 24/7 on the forum handling reports it wouldn't go over a certain amount (and if you check the mod payments over a few months you should be able to work out roughly what those limits are).
