As pointed out here, one can approve a maximum of 3 edits from a specific user per day to prevent gaming.
Could this be relaxed a bit, maybe on a sliding scale, with one additional vote for each 5k or 10k of reputation?
There is a user making a series of good edits to tag wikis and I'd like to approve them, but I can't. The edits have been waiting in the queue for fifteen minutes now. This is likely to be a bit of a hindrance in the future whenever <2k users go on a (useful) editing spree.
On the other hand, it's sunday so traffic is low. Otherwise, the edits would probably have been approved away within thirty seconds. So maybe this is not a real problem most of the time.
Maybe relax it only for tag wikis, on the basis that they need extra love, and frivolous edits and gaming are easier to uncover there?
