I really have to say this. Actually, I recently created an account for my neighbor's kids because they're very close to my younger brother/sister. Recently, I noticed they've been editing some of my coding contest entries, but instead of changing the original, they even recolored Starpsychic's OC character in scratch.mit.edu/projects/1328352029/. I wrote in the comments asking them to credit the source, but they didn't even bother to read it, and I reported them. When their younger sibling played, they said their older sibling wanted to see me. When I went to their house, they even said they liked it. It's so frustrating! That project took me 30 minutes, not including the editing time I had to do. When I left, I told them that if they didn't credit the source, I would report them. They agreed at the time, but when I checked Scratch in the afternoon, I found they were remixing coding contest 50+ entries that I had created. It did nothing and even deleted some of the things I had noted in the comments about not citing sources, but they didn't respond either.
