I have been able to create a script that bypasses the stop button using only the default blocks of Scratch! Try it, the stop button won't stop the line from spinning! The script is super simple, and is easy to re-make, but the technique itself took a while to figure out. I think the Scratch team needs to fix this, since it could be misused. I myself have no intention of misusing this script, but if you use it, remember that with great power, comes great responsibility...
