how about this: every level 2+ admin can vote to delete a race and if, over time, a race gets more than like 15 votes, it gets deleted (but not forever, just into a recycle bin folder). the number of votes required is just the first number i thought of so we should probably discuss that more cos if it's too high we'll never delete any bad races and if it's too low too many will get deleted. i think this'd be the most democratic way.
