these are all the hacked blocks i was able to get without using @qucchia's hacked block collection project: https://scratch.mit.edu/projects/382631312
You are free to use hacked blocks however you like, but it is important to know the risks of using such blocks, as explained below. - Your project will not be taken down if you use hacked blocks, but projects that feature or showcase a hack could be marked as NFE, according to a Scratch Team member. NFE or Not For Everyone means the project cannot be front paged or appear on trending. This project will probably be marked as NFE, for instance. However, if you just use these blocks to improve your project you should be alright. - In future versions of Scratch, for example Scratch 4.0, hacked blocks may lose their functionality and projects that use them could break. This is what happened to many hacked blocks in 2.0, so be very careful in using them. Think about what would happen if your project didn't have that hacked block you're using. If it would totally break, you should probably remove it and find a workaround.
