I consider myself lucky to have grown up before the internet, but after local BBS' were a thing. My parents had absolutely no idea what went on in those systems, and I found the freedom incredible. Being able to explore and spread my wings a bit was a huge part of my childhood and teen years, and it wouldn't have been possible if my parents were hovering over my shoulder, or if I were unable to make an account because I wasn't 18.That said, I was mostly dealing with griefers in Trade Wars or LoRD, and the worst thing I could find locally was GIFs of women in bikinis (and waiting for them to download was an excellent way to learn patience). I didn't have to worry so much about the threats that exist today online.
I am so grateful that I grew up when I did and got to experience that.
