So I tried the Diamond Ride.
IT WORKED!
I got my 1.000 starcoins!
If you think I'm lying, ask goth89, she was there,
plus I was on the phone to her and she kept saying 'DO THE DIAMOND RIDEE!!!'
So she got about 500 starcoins aswell! 
And after I did it, lots of people gave me autographs,
so thanks for the support. ♥
