Got expelled from college. Is this illegal?

[zootreeves]

I found out that my school uses typo3 (Ready made template software) to
manage their intranet and that they had not changed their default
username and password (It was just user:admin & pass:password). I
logged in and changed my sisters report. Anyway they didn't think it
was very funny and i got expelled, just wondering whether anyone knows
whether that is illegal or not (as that was their main arguement)?

>>>Has anyone else on here ever been expelled?

Almost, they were going to expel me from high school for skipping class. But I skipped the appointment to expel me, I dropped out instead. They had the nerve to invite me to a class reunion a couple years ago. I declined and told them I hated going there when I was forced, why the heck would I walk back in that school now!

Of course I enrolled in another school in the next semester.
