Originally from https://github.com/Hans5958/userscripts/blob/master/Scratch/Shorter%20Scratch%20Stats%20Links.user.js. Made better by me. Now with working (hopefully? It doesn't seem too. Userscript developers, please help!) update link and a better name! Make sure to follow me on Scratch if you like it: https://scratch.mit.edu/users/-Xanimation-/
