-RECOLORS AND SUPPORT RECOLORS PROJECTS ARE ALLOWED, IF I SEE ANYONE ADDING ANYTHING ELSE, FOR EXAMPLE, PROMOTING THEMSELVES, THEY WILL NO LONGER BE ALLOWED IN THE STUDIO-
This studio does not support disrespectful recolors or recolors made without giving proper credit, other than that, recolors are fine! Scratch is aimed at young children who want to explore coding, since these children are typically 0-10, Scratch is a coloring book to them.
My 8 year old little sister recolored something respectfully, and got harassed and bullied to the point of being forced to leave her old account on Scratch. This incident happened a month ago, and I'm going to assure you it was all a misunderstanding. We're all cool now, but ever since then I've wanted to spread awareness on this issue.
Yes, Scratch rules state that you can remix anything. You can use anything you find on Scratch if you remain appropriate and give credit. (Even if the project owner says not to, they're still allowed.)
Honestly, if you don't want your art recolored and/or are against recolors and remixes, then Scratch is the worst place to be.
