I remember trying to set up a bbs on my pc in the 80s and I didn’t have a separate phone line so I just put it on while I slept. Then people started calling and annoying my parents with daytime modem calls, because I was like 10 and I didn’t think through any of this.
I set up a uh war dialer around the same age over night and my mom got some pretty upset calls the next day.
She had no idea who these people were or why they were upset. I don’t think I copped to it, it was not an easy thing to explain but I did not do that again.
