Mario Kart Baby Mario
Owners of Mario Kart will have noticed recently that some people have been exploiting some bugs and cheats to give them unbelievably great times in time trial mode.
Thankfully, it seems Nintendo have listened to these complaints and have dealt with them.
Nintendo have deleted the insane times from all records and have removed the cheating methods.
Whether or not said players have been banned from uploading time trails to the server is not yet known (but I doubt it very much), but at least it's a step in the right direction.
