Here's my scratch license, just to say that I'm an official scratcher. Make your own by copying this into your own project and covering it with your information: Profile picture, Username, Join date.
There have been lots of bots, and hackers, and bad people involved with scratch accounts, however this shows that I'm not in the wrong. If you're not someone who is a mean scratcher, raiding studios, having bot accounts, etc... make your own license. That way, we can all trust one another in the scratch community!
