My school has an appeal system where you can send the site to admins along with a short explanation to make your… case? Anyways, I used that when my school blocked it. I don’t remember what I wrote, but I believe I mention that
- It’s made by Microsoft, so it’s not unsafe at all
- It’s an educational resource used by schools around the world
If your school doesn’t have such a process, your teachers 100% have a way to get sites unblocked for students, whether it be an email to admins or just mild admin power themselves. If you have a teacher who you think really likes you (teachers in classes you have good grades in work too!), you could try to make your case to them. You could even go to a counselor or something. If you have good grades and you aren’t coding instead of doing work in class, you can probably make a pretty strong case for yourself. Like @Richard mentioned, it could also just be a mistake, seeing as they didn’t have it blocked for so long.
Good Luck!!!
