Very simple fav-bot for Scratch in Python

from scratchclient import ScratchSession #https://scratch.mit.edu/discuss/topic/506810/
session = ScratchSession("username", "password") #here goes your scratch username and password

infinity = 999999999 #a big number
for i in range(104, infinity): #earliest project has the id 104
    try:
        session.get_project(i).favorite()
        print(i) #so you know that the program favorited a project
    except KeyError: #if project doesn't exist
        pass
