We know that RockBandScores.com is a valuable resource to some players, and that's why we've always tried to support them. We provided them with the API so they wouldn't have to scrape the leaderboards and it would be less drain for both of us.
But at the moment our Web team is hard at work on other stuff, and while I'll make sure it's on their radar, a fix for a 3rd party site benefiting a fraction of our user base likely won't be high on the list of priorities. I'll follow up if they have a time estimate or any updates to provide. Thanks for your patience.
