What if there was a button to thumbs down something? But, it wouldn't give anyone a message, or show the dislikes either. It would just be so that people who rep0rt projects just because they don't like them click that instead of report. You could dislike and no one would know about it. It could also help with haters.

Sorry, rejected.

The Official List of Rejected Suggestions wrote:

4.2 Dislike button or a project rating system
Generally, a user's first project is something rather simple, such as a test project, a remix, or a project made using a tutorial. Because this project is simple, other users may give the project low ratings since it is not advanced. With low enough ratings, the creator might be discouraged enough to stop using Scratch. Moreover, constructive feedback is encouraged on Scratch. A dislike button may show the creator how many people disliked their project, but it tells nothing about what the creator could do better. If you do not like a project, you could choose not to love it, or you could leave a respectful and constructive comment telling the user how to improve, in addition to saying what you like about the project.

With that, a dislike button is rejected for anything, including projects and comments. This also includes a decoy dislike button that does not raise any number in a “dislike counter”; for more information, see this post. However, a like button for comments is NOT rejected. You can discuss it on this topic.

ST reviews every report so false reporting doesn't actually work at all

plus we have the report button, and dislikes are anyway rejected
