Option number three and four. I would look to improve on the criteria that allows a map to be added.
Personally, the first priority of racing maps on the racing server should be the actual racing; that means good mapping that avoids bugs, good checkpoint placement along a racing line and good usage of cars. I do enjoy maps that are difficult or maps that offer variety whilst still having the racing as a priority which is why I would not want to see those deleted. There is a few maps being added though that are there to show off scripting, new mapping objects (some which have terrible clipping issues), or to just be a general annoynance in terms of ridiculous checkpoint placement/usage of cars which is the problem for me.
