Not really hacking AOL, but I found that you could get the passwords in plain text from the Filesystem, which meant I could get around the parental controls and use it when I wanted!
Submitted it to “happy hacker” and it got in the newsletter, I was super chuffed as a 13? yr old!
Edit: I had a thing called “aol admin tools” which I have no idea if it was legit or not but could see lots more than I could normally lol
